I have an Iphone 4S on firmware 6.1.3 and modem firmware 3.4.03. I decided to unlock it using a Gevey Ultra turbo sim. The process worked flawlessly and the phone is now unlocked. I have discovered that if I put back in the original sim tray and sim from the carrier that the phone was locked to I cannot get any signal on the phone but using the gevey sim it works fine. Is this normal after using a gevey sim. I then tried to restore the phone in Itunes just to see would it lose the unlock and work with the ordinary sim tray. First of all I tried restoring from a back up and got a message saying that there was not enough space on the phone even though there is 2.1Gb free. I then tried a full restore and got error -1. Does anyone know whats the best way to get past that error or will I never be able to restore the phone to the condition it was before I unlocked it.
