First, restore your iPhone 4 to iOS 4.3.5.
**Make sure you hold the SHIFT key when you click restore, and then select the iOS 4.3.5 .IPSW file.
Now you need to create a custom iOS 4.3.5 restore file using Sn0wbreeze (follow this guide) and then restore to that custom .IPSW file.
DO NOT activate your iPhone with Apple’s servers.
Power off your iPhone 4 and insert your Gevey SIM along with the SIM card you want to use.
Now power it back on. Wait a couple of seconds for one signal bar to appear and then accept the Gevey SIM screen. Now open the Phone application and Call 112, then wait for 2 seconds and quickly hang up!
Now go to Settings and toggle Airplane mode ON. Wait for 30 sec till you see “No SIM card installed” pop up. Then simply tap ok and toggle Airplane mode OFF.
That’s it, your iPhone 4 is now unlocked on iOS 4.3.5. Enjoy!
