Apple has made a strong intervention in iOS 5 against the Gevey SIM, blocking the magical iPhone 4 SIM from working, which by many analysts is also believed to be an illegal solution for unlocking the iPhone 4, that supports all current basebands. However, a workaround has seemingly been discovered to get the Gevey SIM working on iOS 5 beta 2. Follow the step-by-step procedure given below and you should be able to unlock your iPhone 4 running iOS 5 beta 2.

DO NOT activate your iPhone with Apple’s servers. Follow Gizmodo’s tutorial posted here.
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.
