I have a 3G 8GB carrier is Fido. When I restore the iPhone to 3.1.3 firmware my iPhone works perfect with my sim card. Once I jailbreak the iPhone with redsn0w 0.9.3 everything goes as normal but then iPhone does not read my sim card. If you go back to original factory 3.1.3 firmware my iPhone reads sim card.
is there a solution to this. Please help. :(
