We don’t know if Verizon’s Unlimited Plan announcement had anything to do with it, but AT&T announced today an unlimited plan for the same $99 as Verizon. The plan will be available starting Friday, February 22, and like Verizon’s, it only includes voice calling, data and messaging will cost extra. The plan will be available to both existing and new customers, and anyone can get it month-to-month with no contract. We find AT&T’s plan very good for consumers.

Like we predicted about a week ago, the long-rumored GSM Palm Centro is now officially available on AT&T upsetting Sprint’s expiring exclusivity, giving AT&T users access to the amazingly small handset. Unlike Unlike Sprint’s version, the AT&T Centro uses EDGE data for a somewhat slower browsing experience; besides that, though, it features a 1.3 megapixel camera, microSD slot, Bluetooth 1.2, support for AT&T’s push-to-talk service, and a full QWERTY keypad. Price with contract and rebate is $99.99.

AT&T Palm users get ready for the Centro, it’s coming next week. We’ve have gotten confirmation that next Tuesday will be the day that Palm’s budget handset launches on AT&T. We predict the price will be $99, at this time only white color is confirmed; more next week at launch time.
