Would iMovie and GarageBand run on iPad 1 running iOS 4.3? If I don’t get the FaceTime cameras and Photo Booth for now, I’m fine with that. Really hoping it will run on the 1st gen iPad…
I had some issues with iOS 4.3, sometimes it got stucks and I did hard reset. And signal strenth display seems to again increased like in iOS versions 3.2. Display of call history and missed calls are in smaller font,full screen video playing I observed.Phone functionality , I could feel little faster than iOS 4.2.1, hope Apple will release patches very soon.
