OK.. I don't know if this subject exists currently, if it does my apologies.. My father has an old iPhone, 4 or 4s don't remember which.. I think 4s. He doesn't update much, or at all really, doesn't have a steady computer, or one that he works on all the time; basically he's all over the place. what I'm trying to do is set him up so that he backs up to the cloud, but to do that I have to update his phone.. Is it possible to just backup the iPhone, not sync, to a computer, lets say the one in his office, this way after upgrading to the latest os version, if necessary I can restore whatever contents are on his phone currently? Thanks in advance for listening.
