12/2 update - Changed title, since the 15GB for $100 expired on 11/30. For those new to this thread, in October AT&T had an internal promotion whereby they would match Sprint's 20GB for $100 family share promo. AT&T killed this after a few days, as too many people signed up for it. Then in November they offered a 15GB for $100 family share, which expired on 11/30. As of now it appears the only promo is the "standard" doubling for 15GB and higher plans (i.e. 30GB for $130, the normal price of 15GB plans). I will update again if any promos for less than 30GB arise. _______________________________________ The original matching "promo" detailed below died somewhere around 10/27. 11/17 update - Posters near the end of this thread alerted to the fact that AT&T is matching Verizon's promo of 15GB for the price of 10GB. Resendetra noted AT&T has made the match official, meaning nobody has to do the retentions dance to get this promo. I'm leaving original post below. _______________________________________ I'm a pretty new MacRumors forum member, so hopefully I'm not committing a huge faux pas by doing this. It has come to light that AT&T is now willing to match Sprint's 20GB for $100 family share plan by bumping their 10GB to 20GB and leaving the price at $100. This is covered on page 10 of the AT&T Double Mobile Share Data Pool thread. The short version is, you have to call and talk to the retentions department. Tell them you're considering canceling and going Sprint for the 20GB for 10GB price, but you heard they would match. It's pretty easy. Must be done by 10/31. However, I think this is pretty big news, especially for folks like me who took the 30GB offer, but really only needed a bit more than 10GB. Thus, I started a new thread about a topic in an existing thread. I know, people get flamed for this. I think it is warranted in this case because the news is located on page 10 of the thread and I doubt most interested parties will see it.
