It looks like that the "fastest Internet for the price" is going to get a bit more expensive. Cnet reports that AT&T will make certain plans more expensive. If you are using AT&T for your phone, the 1.5 Mb/s service will increase from $20 to $25 and the 3 Mb/s service will jump from $25 to $30. Without the phone, the 1.5 Mb/s service will climb from $24 to $29 and the 3.0 Mb/s from $29 to $34.
At the time of this writing, AT&T is still advertising the old prices.
