I'm currently on iOS 4.3.5 on my iPhone 4. I am unlocked with a gevey SIM on baseband 04.10.01.
Can up upgrade to iOS 5 if I preserve my baseband? If so, can anyone give me a breakdown on how to proceed? Already downloaded the iOS IPSW (iPhone 4 GMS) and the latest redsn0w.

I see that this is a tethered jailbreak- Is it possible to upgrade to iOS 5.0 and have an untethered jailbreak?
