Looks like Acer’s smartphone strategy at Mobile World Congress will involve at least two handsets. The DX650 would be a unique dual-sided phone with a dedicated number pad and small screen on the back to make calls easier. It will sport a 2.8-inch touchscreen and Windows Mobile 6.1 providing full app support on the phone’s front. The DX650 should also have GPS and a camera. 3G over HSPA and Wi-Fi are assumed.

The X960 looks like a more conventional 2.8-inch touchscreen phone and is known to have a fast 533MHz ARM processor and a front-facing camera for video calls to complement a back 3.2-megapixel shooter. It also runs Windows Mobile and carries HSPA-based 3G, GPS and Wi-Fi.

More details should be made public with the start of Mobile World Congress next week.
