Can someone offer some insight to an issue my cousin is having after upgrading from an iPhone 5 to a 5s yesterday? After doing his upgrade, he lost a handful of his contacts and out of his 400+ photos in Photo Stream, only 40 or so are showing up. He did do an iCloud backup before going to the store, and he had all the right settings activated on the iCloud section of "Settings". I'm pretty knowledgable about iOS and Apple products, but I can't figure out why this has happened. If all the settings are enabled and the backup was done before hand, shouldn't EVERYTHING have transferred over for him?
