If I include iMovie with the iCloud backup to save all the movies I have made and then delete them from the iPad, will I be able to pull them back down from iCloud? My end goal is to update to iOS 6, but I don't have enough free space. Most of the space being taken up is from iMovie movies. Is there an easier way to do this and then add the movies back onto the device once it has been upgraded to the new OS?
