Hey, I typically action my update via iTunes but this time I will not have access to my iTunes. So I'm considering doing my iOS6 update to iOS7 update on the 18/9/13 via OTA. I'm not a developer on any beta version. Question is : Update to iOS 7 via OTA. By carrying out the software update via OTA, has anyone any idea how long an update via this route takes, or is it the same as via iTunes ? Thaks.
