Unlock Apple iPhone 3G – Successful Tutorial
CrunchGear had mentioned about the new tool Yellowsn0w which helps in unlocking an iPhone 3G for any network all across the globe. This tool was developed by the iPhone Dev Team and seemed to work fine for some people and many had complains about it, from a small error to some permanent unlock disabilities. I still got an experimental iPhone(was a real phone but was a good experiment for me 
) which belonged to my friend, and he wanted to get it unlocked. I assured him that i would do it, as i wanted to test this tool, and the dev team game me more confidence by telling that if the unlock isn’t successful, it won’t affect your iPhone. The phone would be as it was before.
Then i started the unlocking with QuickPWN iPhone 2.2 jailbreak. QuickPWN is the tool that Jailbreaks your iPhone. You can download the QuickPWN for Windows from here or QuickPWN for mac from here.
A small note: Doing the entire process on mac is a better option, as Apple always easily works with some apple tool or product.
Once you connect your device, the tool will automatically recognize it or else you do it manually. This tutorial is for iPhone 3G, so stick to it.
You need to use the latest 2.2 version firmware to pwn your iPhone. Download that firmware from here. This update can allow you to install the Cydia which helps to run Yellowsn0w after the Jailbreaking is done. If you had already upgraded your phone very recently, to the 2.2 version, then there is no need for an update. Still, if you wish, the QuickPWN tool can download and install the firmware from its interface itself.
The IPSW is built, and then the rebuilding with sending of data from your computer is done. The firmware sending is finished, and you get this confirmation. The QuickPWN tool will need you to follow a few steps that it explains. And everything goes fine if you do it correctly. This ends Jailbreaking of your mobile phone.
Phone reboots by itself -
Before the reboot itself, the Success window would make you guarantee that the jailbreaking is done. You should see this image as below -
After this, you need to install Cydia through the installer, and Cydia would then appear in the list of apps in the iPhone. In Cydia, you need to add the source for yellowsn0w, to download the latest version of the tool.
- Go to Cydia app.
- On the home screen of Cydia, go to “Manage” in the bottom bar, and go the “Sources” section.
- Click Edit.
- Click on Add in the top left corner.
- A small address box opens. Enter the Cydia/APT URL = http://apt.yellowsn0w.com
- Then click on the added URL and you would be taken to the download page of Yellowsn0w.
- These couple images would help you understand the pages.
Now once you have installed yellowsn0w, you will be asked to restart Cydia, and that’s the green signal for successful installation of yellowsn0w to your iPhone.
Follow these instructions which are not given anywhere, and i have tried them and found them successfully unlocking the iPhone -
- After yellowsn0w is installed, go to Settings > General > Reset > Reset Network Settings
- This will clear everything related to your present network.
- Now, switch off the phone, and insert the SIM of network you want and switch on the phone.
- Wait for a couple of minutes, and then remove the SIM, insert it back.
- I got a message “SIM INVALID” but still waited for a couple of minutes and turned the Airplane Mode in settings On and Off. Then wait for a minute.
- You would see the network automatically getting detected and signals being received. I tried doing this with Airtel in India and could make calls the next moment i saw the name in the top left of the phone.
* If you are in U.S., switch off your 3G settings and then do the SIM registration process.
And here is the proof of unlocked iPhone with Airtel Network calling myself -
Thanks to QuickPWN, Apple Dev guys for yellowsn0w which helped in unlocking the iPhone 3G pretty easily which i thought was impossible for me before i started it.
I can assist you if you are in the same process, just follow me @ twitter – sizzler_chetan or contact me! Subscribe to get more tips.
——
For everyone who are not able to do it, here is an advice. Better upgrade your firmware to 3.0 version which the latest one released by Apple and then you will have an option to unlock the phone using ultrasn0w.
If you are not sure how to do that, here is how to upgrade to 3.0 firmware of Apple.
Also if you are using a 2G phone, here is how to unlock iPhone 2G.

Brilliant post Chetan, It’s time now for me to get an Iphone and give it to you for the unlock.
January 4th, 2009 at 5:53 am
it was my phone which we unlocked it seemed difficult and fun as the procedure is easy and not at all harmful to your phone in the long go. .
)
So chetan will become the iPhone unlocker in India i guess. . lol
January 4th, 2009 at 8:24 am
Great post Chetan. Unlocking iPhone is an awesome and thrilling experience. I always enjoy unlocking my iPhone.
January 4th, 2009 at 8:46 am
Thats a nice detailed guide.
I am going to try on my bro’s new iphone… will tell you the results.
January 4th, 2009 at 9:59 am
I unlocked my iphone 3g when the yellowsn0w 0.9.1 came out
January 5th, 2009 at 2:22 am
Hey dude, you really got it going good. I got my phone unlocked perfectly following the steps for T-Mo here in US. I have been unlocking iPhones a long time. However I would like you to add another note: If you got password enabled for whatever reason including Exchange Mail then disable the password and then the sim is recognized in a go.
January 5th, 2009 at 5:53 am
Sorry if its a dumb question.
Since iphone is 200$ in US, is it legal to buy an iphone in US, then break the service contract, unlock it and use it in India ?
I heard that they track such unlocked phones and fine u ?
January 5th, 2009 at 8:35 am
first of all i would like to thank u for all ur efforts to finaly come out with a soluation for the iphone, however i tried everything u guys said step by step and all worked except no matter what i do i cant get a signal can any1 help
January 5th, 2009 at 10:26 am
@I could unlock iPhone 3G with yellowsn0w tool | Chetan Bhawani: Hello Chetan, I have a question, has the 3g to be switched off during the process, and, do I need to have access to wifi during the unlock process? Thanks.. David.
January 5th, 2009 at 1:46 pm
There seem to be so many tricks to “hacking” or messing around with your iPhone..
January 5th, 2009 at 4:22 pm
@David: Good questions.
When you are in the U.S., you need to have 3G switched off to unlock the phone, but access to Wi-Fi is needed for the Cydia app to download the yellowsn0w tool into phone.
January 5th, 2009 at 4:25 pm
@amrish: You might have heard it right, but actually a couple of my friends are using the U.S. devices, but never got tracked or warned after they unlocked and used the iPhone for months.
January 6th, 2009 at 10:33 pm
Thank you for all the info, it all worked, but no signal for simcard, what should I do? i have restarted couple of times with and without simcard, then insert it, but still no signal?
January 7th, 2009 at 1:05 am
@iphonefanza: You should follow it correctly.
Reset network settings and switch off the iPhone.
Then insert the SIM and switch on the phone, wait for a couple of minutes after the phone starts.
Then turn on the airplane mode for a few seconds and turn off the airplane mode.
Remove the SIM with the iPhone On, and re-insert it and wait for a minute.
This is how it worked out for me.
January 7th, 2009 at 4:37 am
THANK You, I got it working!
Now I need to figure out how to get photos & contacts back from before the 2.2 version, any suggestions?
January 7th, 2009 at 4:54 am
@iphonefanza: Did you have things in the iPhone before you unlocked it?
If it was, then I think they are lost already when you jailbroke the phone with QuickPWN tool as the firmware upgrade deletes all the data and makes the phone completely new and nothing is left in it.
The same happened to me, losing all the 70 favorite applications I had, unknowing that they would go with the Jailbreak and unlocking process.
January 7th, 2009 at 5:59 am
it had more that a thousand photos on, which were not backed up to computer. I dont know iphone very well yet, and when i plugged it into the computer for the first time, i had to upgrade itunes, then the iphone said there is upgrade and i just said yes, without thinking/knowing that i had to backup the data. thats when it simlocked, and i could not get into the phone at all. now i can, but have no data.
January 7th, 2009 at 6:28 am
@iphonefanza: That’s sad, and i tried to find out things in my friend’s iPhone and it shows no data. And i find no relevant information on the web about it.
So assume the data toe be lost totally.
January 7th, 2009 at 6:41 am
Thank you Chetan, I will also go in further search, will let you know if i find something.
January 7th, 2009 at 10:11 pm
@Chetan: Thanks Chetan..
January 9th, 2009 at 12:58 am
GREAT WORK! im using My 3G for T-Mobile US and this worked excellent no problems!
January 10th, 2009 at 6:36 pm
Hey chetan,
Gr8 wrk bro!!
Nice to c the phone back in use..
Keep goin
January 12th, 2009 at 10:52 am
@Chetan – after jainbreaking and unlocking, cant we use the backup’s on iTunes to get all the data back? Thx.
January 12th, 2009 at 2:57 pm
Thanks Chetan (and the phone dev team)! I’m on vodacom in South Africa (o2locked iphone) and that worked perfectly, first time. Brilliant!
Is there anything I must NOT do now, to avoid problems???
thks
January 13th, 2009 at 3:05 am
Thank you so much for helping me, do I still have to keep the applications on the IPhone and anything that I shouldn’t do to avoid problems?
January 13th, 2009 at 3:46 am
@Bear: Great to know it worked.
@Nitin: Thanks for the appreciation
@Deep: If you have backup in iTunes, then you can surely get the data back. Many people fail to backup the data and so complain of losing everything. Its good if you have the backup, and so you can get it back into your iPhone.
@Kattbatt: Good that it worked for you too. There is nothing else you need to do, just let me know anytime you see any problems. I might try to help you out.
@Jimmy: Applications do not have any link with the unlocking. Still, the Installer and Cydia apps that you have used to unlock have to stay in the iPhone as of what i saw. After i deleted Cydia and restarted the phone, the network could not be recognized, so keeping them would be good.
January 14th, 2009 at 12:11 am
I know this is a little off-topic, but the Iphone 3G can only accept ring-tones up to 30 seconds? and do you know anything about custom SMS tones?
January 14th, 2009 at 12:44 am
Sorry I don’t mean to double-post, but is there a way to access the Internet without using Wi-Fi? I am with T-Mobile now and using the Sidekick LX with Internet package.
January 14th, 2009 at 3:54 am
@Jimmy: I’m not sure about the internet packages, as what i use is Wi-Fi to access the internet in the iPhone.
And for the ringtones, the 30 second limit is right. I have never tried the custom SMS tones.
January 14th, 2009 at 11:14 am
Thank you so much bro.
after so long strugling with my 2.2 software locked.
i finally manage to unlockd my phone…
Apreacite your help chetan…
Cheers
January 16th, 2009 at 4:12 am
i dont have wi-fi connection…but i have laN INTERNET CONECTION…..WAT 2 DO I AM IN INDIA HELP ME PLZ
January 17th, 2009 at 6:03 pm
Anyone knows if after Unlocking, if I turn OFF the iphone will the Unlock become void? I just turned off my Iphone (which was unlocked) and when I turned it back on – I lost my Phone service totally. Has this anything to do with a Software Unlock issue.
Thanks for your help.
January 18th, 2009 at 6:32 pm
hello every1 now this procedure of iphone unlocking and jailbreaking looks promising..i want help..
i mean i am planning to get an iphone 3g from usa…i can get it but the problem is i am worried if it will not be unlocked…then it will be a total waste for me…so wat do u suggest should i go for 1 without worrying…and also i am scared that whether repeated attempts to unlock my phone may leave my phone permanently tampered and non functional…..wat should i do should i go for a new i phone 3g and then follow the steps u have shown…..or wait longer,…..
January 19th, 2009 at 3:06 am
I have the same problem as jboxer2008
Using a Telstra Service that requires me to enter a pin into unlock.
Once i power cycle the phone it goes back to being unable to get a network
Any further advise would be appreciated.
Please note, this does not happen with a pre paid SIM, only a Telstra SIM account that requires a pin every time your phone it switched on.
January 19th, 2009 at 6:15 am
I’ve turned it off and reset it and I still retain the original unlock features, don’t know whats wrong but the best bet is to probably “restore” it from ITUNES and try it all over again. No harm if you do so.
January 19th, 2009 at 4:55 pm
Thanks Jimmy for your feedback. I am new to this and am afraid to restore anything from Itunes since I read somewhere that it could lock your phones up. I hope to hear from feedback from others otherwise I may have to bring it back to Apple but I doubt they will help since the phone has been modified.
January 20th, 2009 at 1:17 am
Once again Jimmy, thanks for your help. Since I was also having problems with SIM eject. I just went into a local Apple store. The Genius discovered that the eject spring is faulty and offered to exchange another phone – so I got a new phone that is now locked to ATT so I guess I have a new problem and that is to unlock it. I will try following the instructions in here but being a newbie at this I am afraid I might screw up.
January 20th, 2009 at 6:19 am
Just take your time, I know I did. This was also my first time too. I just carefully followed the instructions.
1. Update the firmware to 2.2, just plug your Iphone into the USB and open up Itunes to update it to version 2.2
2. Download QuickPwn, and its firmware on this web-site.
3. Extract QuickPwn and open it up; it will ask you to make sure Iphone is connected and then browse for the “firmware” that you downloaded off this web-page, not from Itunes.
4. Follow the instructions on “jailbreaking” your Iphone.
5. Open up Cydia, it should be installed when you jailbreak your phone.
6. Go to the sources section, edit and add the website — http://apt.yellowsn0w.com
7. Install it, and reset your NETWORK settings
8. Turn it off and insert the SIM network card you want (i.e. Tmobile, etc.)
9. Your all set, I might have missed something if I did, sorry.
January 21st, 2009 at 9:42 pm
Hi Chetan,
I am in US and using iphone3G with AT&T , can you please mail me the detail guide to unlock. it will be good for me.
Thanks in Advance
Sunil
January 22nd, 2009 at 3:06 am
Jimmy:
I have succeeded through patiently reading and following all yours and others’ advice. It now works marvelously with all the various SIMs I have.
Thanks alot.
January 22nd, 2009 at 5:57 am
hey .. when i go to add the source it comes that it did not find repository.. what do i do ?
January 22nd, 2009 at 7:14 am
Glad to be of assistance, we should all be thanking Chetan for his tremendous help though. He deserves all the credit.
January 22nd, 2009 at 3:24 pm
Hi Chetan,
I am in US and using iphone3G with AT&T , can you please mail me the detail guide to unlock. it will be good for me.
I will be returning back to india soon, so can you please mail me the guide or steps.
My email id is jhonty.babar@gmail.com
Thanks in Advance
Sunil
January 22nd, 2009 at 9:23 pm
@bala: Thanks for the appreciation and glad that it worked for you.
@soundar: You can connect the iPhone to your computer and download Yellowsn0w in Cydia through iTunes connected phone.
@Jimmy: Your procedure was exactly what i explained and still happy that you helped few others with it. Happy to see that unlocking tutorial coming into use for you too.
@Sunil: I have nothing special than the step-by-step procedure as given in this post. You can read it and follow the instructions as given in the post to unlock your iPhone.
January 23rd, 2009 at 4:01 pm
Hi Chetan,
Thanks for the kind reply, just one question , right now my firmware version is 2.1, so should i update to 2.2 using itunes and then follow the steps in post, is that right. just let me know.
January 27th, 2009 at 3:29 pm
Hi Chetan,
Can you please help Indians too Chetan.
Could you be able to explain the steps involved in connecting the iPhone (3G) to a computer and in downloading Yellowsn0w in Cydia through iTunes connected iphone.
Cheers
January 29th, 2009 at 3:50 am
Hello Chetan
Any luck with the problem I posted?
If i unlock using your method I have to use a pre paid SIM card, then switch to our other SIM.
If i power off and then back on, it does not work until i put in my pre paid sim card, then switch it over!
As mentioned the SIM we need to work requires you to enter an unlock code everytime you power it on and off
Any ideas or comments would be helpful!
January 29th, 2009 at 5:10 am
@Sunil: There are not many fixes in the new update, so no need to experiment things and upgrade your firmware.
@Maddy: I will soon let you guys know by posting it here.
@Joe: You earlier said that you did it using Telstra network. Did you do the same with any other prepaid service? As i am not sure because i never have worked on any other international networks except the Indian ones.
January 29th, 2009 at 7:03 pm

January 31st, 2009 at 4:39 am
Hey Chetan,
I jailbroke my iPhone a few monhs back. Now I tried to install the unlocking source and everytime I install the source my phone crashes and the source is not installed.
Please Help.
January 31st, 2009 at 6:15 am

Hey, I’ve had my iphone 3g (version 2.2, firmware 02.28.00) since christmas and still haven’t got it unlocked…so annoying! i jailbroke my phone using quickpwn and installed yellowsn0w 0.9.6 through cydia but unfortunately this did not unlock my phone for some reason (even after trying to reboot, toogleairplane mode on and off etc)…so i then i decided to maybe re-install yellowsn0w and try again. ive now installed yellowsn0w 0.9.8 but iphone is still not picking up coverage (still displaying no service!) this is annoying me so much and i really want to get my iphone up and running…any ideas of what i could do to fix this? any help would be greatful.

March 1st, 2009 at 12:00 am
This tutorial works!!! I just unlocked my iphone.
However, DO NOT USE THE LATEST FIRMWARE FROM ITUNES since it has a different base point even though it is still 2.2.1 and will give you FIRMWARE STRING ERROR. I had two iphones and made the mistake of upgrading to the latest firmware from itunes and got the error.
For the second iphone, I did it by downloading the firmware linked in this tutorial, open itunes, hold down shift key and click restore and select the firmware you downloaded. The rest works like a charm.. Thanks for this tutorial. GOOD LUCK
March 3rd, 2009 at 4:57 pm
I dont know what I’m doing wrong but the pwnage tool isnt working for me. I get a error message saying that there is no free space left for the application on the iphone. Do you know what that means? I am using an Iphone 3G and am trying to unlock it. Thanks in advance for your help
March 4th, 2009 at 1:26 am
Okay
When unlocking,do I leave a sim card in iphone or not ? The current sim card it isn’t activated now.
Thank you

one thing i need to mention, when I reset network settings, it automatically restard iphone, then I swiched off the phone manaully. do i have to switch it off as soon as it tries to restart after resetting network?
also the i got yellowsn0w ver. 9.8. may be this is causing any problem?
please help as I am stuck here.
May 3rd, 2009 at 6:31 pm
Hi!
Thanks for this detailed tutorial.My iphone was locked when i installed updates 2.2, and had already been jailbreak with quickpwn, i have been using it as ipod touch when i saw this tutorial. Followed all the steps,i installed yellowsn0w ver. 9.8.reset the network settings and switched on/ off to airplane mode and followed all instructns, but iphone is still not picking up coverage, still displays no service.What do i need to do again, need help urgently.
Best regards.
May 5th, 2009 at 7:40 am
I did this but then there is no iphone function. If I take out the sim card it says “no sim” but there is no phone network with card. Any ideas?
May 18th, 2009 at 1:36 am
I got my iphone jailbroken and unlocked with a turbo sim (but the person did not show me the proof of the same) in the US itself before coming to India for a vacation. But Im not able to get it working with airtel now.. I actually restarted my phone a lot of times… no use.
Help me!!!
May 21st, 2009 at 2:08 pm

May 28th, 2009 at 3:03 am
Chetan,
I did all the steps correctly, But when i put my sim card into the iphone it is not picking up the service any suggestions?
May 28th, 2009 at 6:01 am
i will like to know two quick things:

I have the latest iphone with newest software and boot loader. I’m being told there is currently no way to unlock this version yet. First, is this correct? If not, what else can I do because I tried your instructions and it still didn’t unlock it.

Would really appreciate if Chetan or someone could guide me.
I jailbroke my iphone using quickpwn, installed cydia and installer as instructed in chetan’s tutorial but am stuck at the step in which you are supposed to download yellowsnow through the phone.
I got my iphone from US(ATnT) where i had a data plan but now i have no internet/wifi on my phone. Was wondering if ther is anyway i can download it through my PC ?
Could you be able to explain the steps involved in connecting the iPhone (3G) to a computer and in downloading Yellowsn0w in Cydia through iTunes connected iphone ?
June 12th, 2009 at 3:47 am
Seearched for yellowsn0w on itunes but couldnt find it, also tried to use the link http://apt9.yellowsn0w.com , it just takes me to a blang page. Does anyone know a link to download yellowsnow ?

wakar, it’s easy to solve your problem. just remove your sim card from your iphone. put the sim card in another phone and make a call. then remove the sim and put it back to your iphone. it’ll work.
June 22nd, 2009 at 3:01 pm
abby, what firmware do you have now? send me your e-mail i’ll forward you a step-by-step guide to get to yellowsn0w to unlock your phone. it’s pretty easy to do after you’ve jailbroken the phone. i finally summoned the courage to unlock by phone over the weekend and it works fine without a turbo sim and all the lost signals.

@ ken koh – thanks!
i finally installed the yellowsn0w on my phone and followed exactly the steps listed above after installing yellowsn0w but i still dont see any network after restarting with the 3rd party sim(vodafone in my case). Where do u think i might have possibly gone wrong ?
The firmware that i am using is 2.2.1 (i have a 3g).

Hello
(
please help me
June 27th, 2009 at 3:33 pm
abby, you had made it this far, it should work. switch off data roaming and 3g and reboot. then go and do reset network settings. if still doesn’t work, try switch the airplane mode ON and OFF. if still no success, the last option might be to reinstall everything from quick pawn to yellowsn0w but this time put in your third party sim card in. it should work. reboot once or twice and wait. it might take 30 min in some cases. good luck
June 27th, 2009 at 5:01 pm
abby, i’m beginning to think you’re in the same dilemma as those users with version 2.2.1 and baseband 02.30.03. until the dev team came up with a new version, current version of yellowsn0w can’t unlock your iphone. good luck.

I bought a iphone 3g from airtel with 3.0 can I unlock it and use BSNL sim. Please reply
September 4th, 2009 at 6:14 pm
Chetan…you rock…managed to get my 3g working again…however..it doesnt pick up any wireless signal…im pretty scared cause many ppl seem to have the same problem and they seem to think its a hardware issue…and apple is def not going to replace an unlocked iphone..do you know anything about this?
September 5th, 2009 at 1:07 pm
Richee,
You can try unlocking it with 3.0 as I never tried doing it with BSNL SIM card, so not sure. Sorry! Btw be caureful with the firmware version. Don’t be in a hurry as the latest versions which are the improvements from 3.0 are actually built to permanently disable the unlock function. So don’t upgrade the phone to latest firmware.
Akhilesh,
Yes i too have noticed people complaining about it. Why don’t you try to reset the phone settings manually from the phone than to play with the firmware once?
Let me know if anything works, as I didn’t encounter any problem in the past related to wireless network.
September 24th, 2009 at 1:04 pm
Thanks Chetan, to jailbreak WiFi or EDGE is necessary I don’t have WiFi I don’t know about this is the EDGE & GPRS is the same.
September 24th, 2009 at 1:15 pm
sorry I didn’t complete I had only GPRS connection
October 3rd, 2009 at 5:35 pm
Hi Chetan,
Thanks for the great article, I would like to know one thing i.e do you need ATT sim to unlock it. I’m planning to get iphone 3G the unlocked one but that may not have any ATT sim.

download Blackra1n RC3 from tis link
http://www.blackra1n.com. NEW Firmware 3.1.2 with baseband 05.11.07
November 8th, 2009 at 9:37 am
n the site you will picture of George Hotz, there will sign for windows and mac click on windows picture and Blackra1n will be downloaded to the computer. Now connect iPhone via USB run Blackra1n click “make it rain” wait it will automatically jailbreak George Hotz picture jailbreak is complete open iPhone one Blackra1n in second screen. Open “Snow” it will automatically unlock it very easy.[for the jailbreak to work first time itself - "make it rain" when the screen gone blank hold both home button & power botton at the same time and when you see apple logo leave power botton hold on the home button until you see the George hotz.]
November 9th, 2009 at 11:22 am
Jailbreak may not work some times it takes several attempt. if jailbreak didn’t work or something happens hold the power botton and home botton until it restarts.

Hi, I got my iPhone unlocked OFFICIALLY, which I had got from Airtel 13 months ago. It was painful though. For 1 week, I wrote mails to NodalOfficer.KK@airtel.in & 121@airtelindia.com, but it did not help.
Then my friend visited the Airtel Showroom where I had bought the iPhone. And those guys finally got it unlocked. I had send them email at kk.brandshop1@airtel.in.
Total time taken : 2 weeks
Actual unlocking : 1 day (rest of the time went in just emails & visiting Airtel)
The Airtel interface that worked: Airtel showroom where I had bought the iPhone.
Earlier, on request, Airtel unlocked iPhone after 12 months. Though currently it seems that Airtel no longer officially unlocks it http://support.apple.com/kb/HT1937.
Now I am successfully using my iPhone in Finalnd with a local operator.

Hi Chetan,
I am from Australia. I have this new Iphone 3g (8GB)got from Optus service provider as a replacement to old damaged phone. But I have already lost he sim and have my contract cancelled. That means I have phone brand new but unlocked. How do I register this phone with a prepaid sim & same time unlock it to work. O dont even know how to load Itunes in it. Please help me?
February 13th, 2010 at 12:58 pm
Shashi,
You first need to know what iTunes software is. It should be there in you computer. Do you use Windows or Mac OS?
Also, you can place another SIM and follow the above procedure after you check about iTunes and start using it.
Let me know!
