Received the phone a few hours ago, updated it to iOS 9.1 PB 2, reset (erase all contents and settings), and then started the restore from iCloud. The phone just came out of the initial restore phase and I can finally see / use some of it. The top portion (top 1-1/2 to 2 inches - front and back) of the phone is scorching hot. Hotter than any other time I've felt an iPhone. Did I just overwork the thing? During all this time its been sitting on my bed in a room cooled to 68º.
