Is there any real difference between an iTunes iOS upgrade and an OTA upgrade?
Why I'm asking is that there were some glitches that I was having on the iPhone after the OTA upgrade from iOS 8.1.3 to iOS 8.2 and I decided to do a full restore of the iPhone.
I figured, what the heck? What will it cost me? Half an hour? Big deal.
So I plugged in my iPhone to my desktop, performed a backup, and then told iTunes to do an iPhone Restore. It then proceeded to download a full copy of the iOS 8.2 installation file (2.2 GBs of data) from Apple and then put the device into... I don't even know. It reloaded the OS or at least it appeared to do so. It then walked me through the whole process of restoring my iPhone backup.
Half an hour later and I'm back up and running on my iPhone, minus the weird glitches.
Why? What happened? What got fixed? How did it get fixed? What fixes were done by doing this long procedure?
