I have been public beta testing iOS 10 for a while now. And since the GM version is officially out, I've been wondering if it is still a valid point to full restore instead of using OTA? I have an iPhone 6s Plus and everything is butter smooth but still wondering if that was a clean install given that the size of the OTA update was 1.79gb? That is, erasing everything and starting from scratch without using a backup. (Eventually when the official iOS 10 comes out on the 13th) I'm so used to doing a clean restore via iTunes since iPhone 3g so I don't know if things have changed in terms of installation clean up with OTA.
