Hello everybody! I am very new to iPhone, one week of jailbreaking and unlocking, but no results. I'm from Latvia and I get iPhone from England, the phone is locked. First it had iOS 5.0.1 and modem 06.15.00 and old bootroom, but I couldn't unlock it to our Carrier (With Ultrasn0w). I have saved SHSH for iOS 4.1 and 4.3.3, of course I downgraded to these versions, but still I got "No Service". In Settings-General-About I see may Carrier (LMT 8.0). iPhone works fine, I can play games, use WiFi and GPS but can't call and send SMS. Can someone recommend what to do?
