It came jailbroken on iOS 4.3.5. It has baseband 04.10.01. I want to unlock it using Gevey Sim Card. Before I do that, I want to unjailbreak it. Any ideas how to go about doing these two things? On another note, I want to upgrade it to iOS 5.0.1 (will preserver baseband of course). Is this possible once I unjailbreak? Thank you!
