I'm loving iOS 5, but there's some issues to work out. First of all, my icloud email doesn't show up in the mail app, but it show's up on my mac. Second problem, i can't get itunes sync to work. i plug it in and wifi is on but the sync button is greyed out. and my third issue is it's telling me im almost out of icloud space, but my backup is only 1.6gb total, i should have 3.4 left. any thoughts?
