I just jailbroke my iPhone 3GS with 3.1.2 firmware BUT it has the correct iBoot-359.3 It all went well but there is no cellphone service. I'm on AT&T, so I don't need to unlock. I seem to see conflicting instructions on the proper way to use Pwnage Tool. 3.1.4 to get my phone working. Do I have to start over? Do I check or uncheck Activate? Do I want to update baseband or not? Also, I read it's bad to restore the phone from a backup, because it causes fast battery drainage. True? If I did everything right, how do I get the cellphone service working again?
