My cousin is visiting and her phone still has iOS 7 and she wants 8. She hasn't been able to upgrade because of space issues and doesn't sync with a computer (and is very tech un-savy). I wanted to use my computer but don't want to accidentally overwrite all of her pictures and videos and stuff. I tried searching but found mixed answers as to whether it would work or not, most of them older results. I haven't even tried plugging it in yet for fear it might start erasing and syncing. Just curious.
