Do you have your iPhone 4 unlocked using Gevey SIM and want to upgrade to iOS 5? If so, you can unlock iPhone 4 running iOS 5 using Gevey SIM but you’ll need to follow few steps before doing that. In order to unlock iOS 5 with Gevey SIM, you’ll need to preserve your unlockable iPhone 4 baseband.
You’ll need the new Redsn0w’s “Custom IPSW” option which is included on Mac OS X only. Windows version of Redsn0w 0.9.9b5 coming soon along with new Ultrasn0w later today to unlock iOS 5 (only for current unlocked devices, no new unlock).
You’ll need to download iOS 5 from here, iTunes 10.5 from here and Redsn0w 0.9.9b5 from here. Now you’re ready, below is the guide to preserve iPhone 4 baseband.
STEP 1: Connect your iPhone 4 into you computer then open Redsn0w 0.9.9b5.
STEP 2: Now select Extras then “Custom IPSW” option so that you can create your pre-jailbroken custom firmware.
STEP 3: Redsn0w will start cooking your custom IPSW and you’ll get it in few minutes.
STEP 4: Once you get your firmware, select ‘Pwned DFU’ from RedSn0w.
STEP 5: Follow the on-screen instructions to get your iPhone in DFU mode.
