I've been trying to update my iPad to iOS 5 for 4 hours now. The update finally completed, but now all of my music and photos are missing off the device. I tried to sync my music and photos back, but it's telling me I don't have enough space because there's a 45 gb "other" segment on there that I have NO idea what it is. Further, it's telling me my music is already sync'ed, but it definitely isn't there. Then there's iCloud. iCloud told me I can't use it until I respond to a confirmation email. I never got that. I was looking forward to this so much but now I'm terrified to go anywhere near my phone with this update.
