I tried to update my iPad 2 to iOS 4.3.5 (from 4.3) today and just after it finished extracting software an error popped up and said that my iPad was not eligble for this build. The same thing happened when I tried to update to 4.3.4. What can I do, I really want the iCloud music and app downloads now and I want to make sure that this won't happen agian when I try to upgrade to iOS 5 in the fall. Anyone that can help?
