I was doing a sync tonight when my iPhone stopped 80% through it was an unknown error (39). Tried again, this time lightening the load on the Sync. Still same error. One more time and I decided to restore. 60% through the Restore is gave me this Error message: "The iPhone "iPhone" could not be restored. An unknown error occurred (6)." After spending 1.5 hours with a very helpful but puzzled Apple care Rep, he gave me an ID number and is sending me to an Apple store with a request for a new phone if they can't fix it there. If anybody has any suggestions or has heard of this, please advise. Thanks!
