Note that this call will not connect to an emergency service. Press your iPhone’s home button.

WarningIf these steps fail to unlock your GSM iPhone 4, you might have taken too much time to complete some of the step that require immediate action. Reboot your iPhone 4 and repeat these steps 3 to 4 times.

If all methods fail to unlock your  GSM iPhone 4, either your chosen carrier SIM card is too old, you damaged your chosen carrier SIM card when cutting, your files on your GSM iPhone 4 have been corrupted, or you have received a defected GEVEY turbo SIM. Before calling for support, you should request a new micro SIM from your preferred carrier. A new micro SIM solves over half of all GEVEY unlock problems.

If you would like to keep your current Apple iOS and your GSM iPhone 4 is not Jailbroken, first backup your iPhone data with iTunes, and then perform a factory reset from your iPhone [Settings → General → Reset → Erase All Content and Settings]. Do not restore your data to avoid re-installing a corrupted file to your iPhone.

After performing a factory reset, please repeat the unlocking process. Once you have successfully unlocked your GSM iPhone 4, you can restore your previous backup through iTunes.

If you would like to update your Apple iOS to the latest version, or if your GSM iPhone 4 is jailbroken, you will need to wait for a custom upgrade to be released for the iOS version you want to upgrade to. Based on past history, the custom upgrade should be available within a couple weeks after the latest iOS update is released by Apple. Follow GEVEY on Twitter for the latest updates.
