okay just got off the phone with att rep....
for those who are with att and are grandfathered in with their data plan please listen up....
if you order on line, go into a store... unlimited data is no longer an option to switch over or add, you would be put on and or have to select another plan for now (3gb, since it is $30 as well would be the best choice)
before pre ordering this phone... call att and let them know you will need them to submit the request to attach your grandfathered data plan back once you get your iphone 5 on the 21st
they will note your account (i even had them send me an text to confirm my request, they did) and switch it back to your grandfathered plan, maximum time it takes to go back is 2 weeks
so basically, call let them now to let them know to put you on the 3gb plan for now, and on the 21st you will be calling back to have them switch it back to unlimited get confirmation of your request.
also, you can dial 611 on your att phone to order through att directly at 12:01am pst
that is all....
