Phones Programs/Partners - 10,000 AA or Delta miles for AT&T wireless

hello. i don't know whether this has been posted previously, but in any case, you can get 10,000 miles on either AA or Delta for service with AT&T wireless. I received some promo material in the mail. The terms for both are 5,000 at signup, and then 5,000 after 6 months.

Each program has their own separate # to sign up. To get miles for:

AA: 1-800-449-1672
Delta: 1-800-264-9179

Sorry if this is a duplicate post.
