Initially Dell reps said the phone would just be available in China. However, with AT&T falling behind the android market share it would make sense to have a proven product.
Unlike the Chinese version the AT&T version will have Wi-Fi and 3G. The phone also comes with 850 and 1900 MHz bands, a 3.5-inch 640×360 touch screen display, A-GPS, built-in support for Microsoft Exchange, 3 MP camera with autofocus and flash, microSD card slot, and a virtual keyboard. Unfortunately, there are no specs as to the horsepower, ROM, RAM and screen type.
