Gevey SIM is a hardware-based unlocking method for iPhone 4 which works with most basebands and a reader who has tested Gevey SIM on iOS 5… and it works! It involves using a thinner-than-normal SIM card which actually needs to be inserted along with the actual SIM card into the SIM slot and you have to follow a few steps such as dialing an emergency number (112), turning Flight Mode off and on etc. to unlock your iPhone 4. It works without jailbreaking. The method is a controversial one as its legitimacy is questionable based on the fact that it is not exactly right to misuse emergency calls and after unlocking iPhone 4 on baseband 02.10.04 and 03.10.01, 04.10.01 GEVEY Turbo SIM interposer managed to unlock iPhone 4 on latest beta firmware iOS 5 (developer build).
One of our gracious readers just forwarded along two screenshots from his iPhone who managed to unlock is device running on iOS 5 BETA baseband 04.11.04. The image clearly shows the device operating on unofficial carrier (Turkish Vodafone). GEVEY SIM now supports unlocking iOS 4.0, 4.1, 4.2, 4.2.1, 4.3 on baseband 1.59.00, 2.10.04, 3.10.01, 04.10.01 and 04.11.04.
Make a note that in order to stay unlock it needs to be with the phone. If you switch off your iPhone or battery drains out, you will lose unlock and you need to follow the entire unlocking process again.
