I have an iphone 4 which is unlocked with Gevey Sim on ios 4.3.3. How can I update to ios 6 or ios 5 without losing the unlock. The phone is not jailbroken.
I tried upgrading to ios 5.1 by preserving the baseband but apple isn't signing ios 5 anymore. I have heard its not safe to update to ios 6 by the same method. I don't want t take the risk as i don't have any SHSH blobs saved. Please help. All the nice apps and games require ios 5 these days.
Model : MC604C
firmware: 04.10.01
A way to factory unlock the phone will also be appreciated.
