Related question: how do I transfer my AT&T data plan to the new iPad? I was one of the original purchasers in 2010 who managed to squeak by with the unlimited data plan for $29.99/month before it was discontinued. (Of course, we now know that AT&T is throttling those on grandfathered "unlimited" plans who go over 3GB/month....but oh well.)
Obviously, I want to transfer my unlimited plan to the new iPad, and two years ago I was promised that I could do so as long as I kept the account current. Is it just a question of calling AT&T and providing the IMEI number of the new iPad? Or will I face a lot of problems?
