[lokster]

Hey guys is it possible to upgrade to 4.1.2 from 3.1.3 today? i dont want to upgrade to 4.2 because of the baseband ipad needed to unlock it.

i need this phone unlocked and also its on bootrom 5.08.

can i upgrade from 3.1.3 jailbreak, refresh to 4.1 and rejailbreak to 4.1?

thanks guys

You can use PwnageTool v4.1.3 to upgrade to 4.2.1

You don't have to upgrade to the iPad baseband to unlock since 3.1.2's baseband is already unlockable.
