Hi, This is my first post here, I tried to read and google before posting ... - I have a 3G on 4.2.1 - I upgraded to iPad baseband in order to unlock after. My problem is it can't boot ... always stuck on the apple boot logo. I tried "just restore tethered" but no sucess. I tried to re-install 3-4 times the iPad BB too ... What should I do ? Thanks !
