Do you think it will require iOS 4.3? I want to buy it but I'm jailbroken on iOS 4.2.1 and I don't wanna lose my jailbreak just for that. Maybe there's a Cydia tweak for iPad I'm unaware of that allows apps that "require" you to update to the newest firmware in order to run the app to run on an older firmware? I don't know if what I just typed made sense but if it did, does anyone know of any such tweaks or have a clue on whether or not I'll need to update to iOS 4.3 so I can use GarageBand? Any help is appreciated.
