AT&T is going to have a stellar fourth quarter with a number of devices from Samsung, HTC, LG, Research in Motion, and others running Android, BlackBerry, and Windows Phone operating systems. First up, this weekend, the carrier may actually let the Flipout out of the gate, which has been long rumored for launch on AT&T. The Flipout is said to be arriving this weekend.

Then, on October 3rd, AT&T will be bringing two BlackBerry devices to the market–a BlackBerry Curve 3G along with the BlackBerry Pearl 3G–both are incremental upgrades from their non-3G monikers to add 3G data support, which means you can talk and get your BlackBerry addiction going on at the same time for simultaneous voice and data on these popular, consumer-oriented BlackBerry smartphones.

On October 7th, Motorola’s going to make a return on AT&T with two devices–the Bravo and the Flipside. There’s not much known at this time about either models, and Engadget Mobile, which got the leak, is speculating that both devices may be Android devices. We’re going to be speculating that the Flipside could be what’s floating around as the Chindi.

And alas, the carrier’s bound to have some Windows Phone 7 devices from Samsung, HTC, and LG on tap for the end of the year as well. Coupled this latest leak with the leaked lineup from AT&T and we’re going to wager that the carrier’s in for a strong fourth quarter.
