I bought an open box iPad but I can't restore it because have the Apple ID of the previous owner what should I've to do? My other problem is that I bought it at best buy in Baltimore, MD, 4 days ago when I was in my vacations and now I'm again in my country and I can't returned the iPad.
Thanks for understand me!
