Hi. Well I'm not too good at this but here's the story. I buy an iPhone. I get a T-mobile microsim from their store. Insert, doesn't work because on 4.3.5 (made typo, sorry). Get gevey. Use gevey, works good. Save SHSH using TinyUmbrella. Check the preserve baseband option making sure. Update iPhone 4 to stock iOS 5. Gevey doesn't work. Baseband is 4.11.08. Cannot unlock. Basically, what do I do? I saved my SHSH files this time just in case. So can anyone please explain how I get iOS 5 to be on my iPhone 4, but also unlocked using Gevey. Thanks.
