Gevey SIM to Unlock iPhone 4

Ever wanted to unlock your iPhone at easiest way possible? Maybe you had acquired an iPhone gift abroad and found out it will not work in your local carrier for the reason that it was not unlocked.

Here is a solution that will unlock your iPhone provided that the firmware is 4.1, 4.2.1, and 4.3 with basebands 2.10.04 or 3.10.01. This is designed for people who cannot wait for software in unlocking their iPhone 4. By the way, what is Gevey SIM? Actually, it is not a SIM card but a SIM interposer. It is an electrical interface that directs the connection from one socket to another. A Gevey SIM has an integrated circuit that will unlock your iPhone by dialing emergency number 112.

Here is the brief procedure in unlocking your iPhone with Gevey SIM:

1. Switch OFF your iPhone. Place Gevey SIM with your SIM card on top in the metal SIM tray.
2. Insert the SIM tray and turn ON your iPhone.
3. Select “ACCEPT” in the welcome menu. Wait for the signal bar to appear.
4. Once the signal bar appears, dial 112 and hang up within 2 seconds.
5. Turn your Airplane Mode ON and turn it OFF right away.
6. It will display “error-SIM card” and “no SIM-card inserted.” Click OK.
7. Again, turn ON and OFF your Airplane Mode for one time.
8. Error messages will appear again and in a few seconds the signal will show up.

There you go; you have an unlocked iPhone 4!

Please note that exact procedure must be followed to let Gevey SIM work perfectly. Otherwise, you have to repeat until you’ll succeed. In instances your iPhone will be drained from power, looses signal or rebooted, then you will also repeat the procedure to unlock using Gevey SIM.
