Rumored specs for the device include Android 2.1, HTC Sense UI, and a slide-out QWERTY keyboard, which the phone pictured above may possess. That phone was reported to have AT&T 3G friendly bands, and since the phone being unveiled on June 7th is supposed to be exclusive to AT&T, and we haven't heard anything else regarding this device, there is a good chance that the HTC PC70110 above is that device.
Engadget remarks about AT&T's Android line-up by saying that "one thing's for sure: AT&T seriously can't get enough Android hardware right now." Assuming that this rumor is correct, AndroidandMe makes sure to take an optimistic view by wishing that "hopefully the Aria improves upon the unique experience offered by the Backflip."
