NYSole, mine took about 2 hours and 15-25 minutes...and I was so exhausted that I lost track of what my iPhone was doing. All I know is that I didn't have to go through all that restore crap! But, I was unsure of the process and wanted to transfer my iTunes music/videos, and I was following someone else's advice and I did a restore and lost all of my music and video in the process. The advice came from my ex-brother!!!😱
