If you have a Gevey Ultra, chances are that you’re not able to use it properly since iOS 5.0 was released. Now that the untethered jailbreak is available for iOS 5.0.1, you can patch FuriousMod to make it fully working again. Follow the steps below:
Step 1: Install iOS 5.0.1 on your iPhone 4 using custom firmware to preserve your baseband.
Step 2: Jailbreak iOS 5.0.1 using redsn0w 0.9.10b3 or Corona by following the steps here.
Step 3: Add the following source to your Cydia Sources to install it.
That’s all to it! If you have an older Gevey Turbo SIM just use the 112 steps which you should already know by now.
Please note that baseband 4.11.08 is not supported!
