I have a 8gb Iphone 1.1.4 already unlocked and jailbroken. My question is if I update to 2.0 will I be able to unlock my phone for T-mobile again? I know the dev team is working on pwnagetool 2.0 but is there another way I can unlock 2.o for T-mobile before the release? I see them on ebay unlocked what tool can i use to do the same?

Thanks!
