    So by accident i updated to 3.1.3 dont ask how it happend, but it did and i managed to downgrade the OS down to 3.1.2. I figured out all that SHSH stuff but now i cant unlock my phone. Its jailbroken but for some reason i get no tmobile logo. I dont know what else to do or if there IS anything to do. Im new to this so please have mercy. Thanx ahead.

    I forgot to add, im guessing its the base band because its still on 05.12 as it was in 3.1.3 =[

    Baseband is permanently upgraded.. you're stuck without an unlock for now.

    So i get no signal because of the baseband right? its just not letting me unlock it for other carriers?

    All the new baseband means is that you cannot unlock the phone. It shouldn't be causing your iPhone to have no signal if your phone is locked to the carrier you're using.

    Happy with an iPhone. No iPad needed.

    You get no signal because your phone is now locked to at&t, so it doesnt "see" tmobile anymore.
