After people scratching their heads for the jailbreak after they had upgraded to the latest iPhone 3.1 firmware lately, finally the iPhone dev team has launched the jailbreak option for the firmware but not for all the devices. Pwnagetool 3.1 for Mac OS X is released.

Here are the devices which CAN be jailbroken when using 3.1 firmware –

• iPhone 1st Generation (2G)
• iPhone 3G
• iPod touch 1G

Devices that CAN NOT be jailbroken right now with the Pwnagetool –

• iPhone 3GS
• iPod touch 2G
• iPod touch 3G

Only if you could successfully jailbreak the iPhone 2G and 3G with this Pwnagetool 3.1, then you can add Icy/Cydia app and continue with the iPhone unlock process.

If you are using an unlocked iPhone 3GS, you still need to wait until the Dev team does something for the baseband in it. As, there are reports that the upgrade to latest firmware in them locks the phone and there is no option to unlock the phone right away.
