just got a new iPad air 2 and I did a backup on my iPad air first. Then I told the new iPad to use the cloud to setup. Well the new iPad had ios 8.? so it would not setup because the cloud backup was with iOS 8.2. So I decided to set it up without the cloud and then I decided to update the software to 8.2. It's been doing that for 4 hours now and it looks like it's only half done. If I get the iOS upgrade to work how do I set the new iPad with the cloud info so all my apps and settings are there?
