I basically know nothing about how to unlock or jailbreak an iPhone 4 so please bear with me: I currently own an iPhone 4 version 4.3.5 with a baseband of 4.10.01. I know as of right now I can't unlock this version without the Gevey sim. I'm very eager to upgrade to iOS 5 but I really want to unlock my phone as well! Will the Gevey sim work for iOS 5? I don't want to purchase it and end up wasting my money. Currently, does it look like there will be another way of unlocking with iOS 5? Thanks for any help.
