Question guys: I'll be loading my iOS 7 backup onto my i6 when it arrives Friday. Is it still recommended to put the newly opened iPhone 6 with iOS 8 pre-installed into DFU mode and manually re-load the iOS 8 firmware onto it, and then restore my iOS 7 backup onto the phone? Or is it cool to just pop that fresh phone into iTunes and load my previous backup right onto it? I think I remember it was recommended to wipe the pre-install'd OS back in the day, but I could be wrong. Let me know guys! Thanks.
