5 minute download.... 15 minutes to install and update the iPhone.
After updating the phone, and while the phone was restarting, iTunes notified me that a new iOS 10.0.1 was available for my phone. LOL... I'm like yeah, you just got done installing it on my phone, what do you mean do I want to install it now or later.
Hit, later and let the phone finish rebooting.
Updated to iOS 10.0.1 now...
iPhone 5 w/ 16 GB... iOS 10.0.1 (Build 14A403)
Had to turn off BlueTooth again, but otherwise smooth and no problems. There was a long pause about 75% of the way through the reboot that had me nervous. Lasted about 5 minutes... then suddenly finished on the progress bar and smooth from there.
No swipe to unlock... confused me for a few minutes as other things came on the screen when I swiped. Then eventually saw the press home to unlock... LOL
It's different... But, it's running smooth.
