My lady friend was trying to help her mom upgrade her iphone 5. The iphone was completely out of space when they started the upgrade process so I told them to delete a few things, which they did. They were able to upgrade the iphone but now with IOS 8 she has 12gigs of free space and the back up is 13gigs. She basically just wants her texts back as she was able to still sync her photos, contacts and apps. Any ideas?
