ok so i just jailbroke my iphone 3gs 6.1.3(old BR) today and did the whole ipad baseband thing and my baseband is now 05.13.04. so it is a bell iphone from canada and i used ultrasn0w to unlock it which it worked because in my about screen it shows the change of carriers from bell to fido. but im not sure if my problem is with ultran0w or the fact that i am using a micro sim with a big sim adapter. so yeah im sorry if im not being very clear here but i did cover everything for my problem. o and the iphone just keeps searching and saying no service. now idk if by a small chance it will just fix itself and connect to the fido service but iv had it unlocked with ultrasn0w for about 3 or 4 hours now. so yeah please help cause iv bin searching all day now and iv tried everything there is on the net thats suggested. please help!!!
