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.

**Before you proceed, make sure you have a paid Apple Developer account and access to Windows. Also the Gevey SIM should not be in your iPhone 4 till the end of Step 4.
Requirements:
- iPhone 4
- Download iOS 5 Beta 2 firmware for iPhone 4 GSM
- Download Sn0wbreeze (latest version)
- Gevey SIM
Procedure:
Step 1:
First downgrade your iPhone 4 back to 4.3.3. (follow this guide).
**Make sure you hold the SHIFT key when you click restore, and then select the 4.3.3 IPSW. file.
Step 2:
Now you need to create a custom iOS 5 Beta 2 restore file using Sn0wbreeze (follow this guide) and then restore to that custom .IPSW file.
Step 3:
DO NOT activate your iPhone with Apple’s servers. Follow Gizmodo’s tutorial posted here.
Step 4:
Power off your iPhone 4 and insert your Gevey SIM along with the SIM card you want to use.
Step 5:
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!
Step 6:
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.
Thats it, your iPhone 4 is now unlocked on iOS 5 beta 2. Enjoy!
