The device has a 4.3-inch LCD with 800x480 resolution. Processing power comes from a 1GHz Qualcomm Snapdragon processor. Rounding out the specs are a 5-megapixel camera, GPS and Wi-Fi, along with a microSDHC memory card slot and a 3.5mm headphone jack. Pricing and a release date for the US market have not been revealed, though it should ship in the early part of the year. [via MobileTechWorld]
