I stupidly upgraded my iPhone to 2.0 without understanding that it can not be unlocked. I originally used zIphone to unlock and jailbreak my phone and I know that it downgraded my bootloader to 3.9. I iinstalled iTuned 7.5 and have tried to restore my iPhone to 1.1.4. I get an error 1015 and the iPhone fails to restore. HOwever, I can use iLiberty to kick it out of restore and then proceed to use iLiberty to jailbreak. However, I have no service after jailbreaking and unlocking. Does anyone know a method I can try to get my service back?
