According to a leaked accessory sheet, the HTC Ville and Huawei Prism are headed to T-Mobile in the U.S. The sheet, a screenshot of which was obtained by TmoNews, provides little information outside of device names and “warehouse arrival” dates for various accessories. Accessories, which sometimes arrive weeks before a handset launches, are set to arrive for both devices in early April. BGR exclusively reported this past November that HTC will unveil the Ville at next week’s Mobile World Congress trade show. The device is rumored to be thinner than Apple’s iPhone 4S and will feature Android 4.0, Sense 4.0, a 4.3-inch qHD Super AMOLED display, a 1.5GHz dual-core Snapdragon Series 4 processor, an 8-megapixel camera, HSPA+ and a 1,650 mAh battery.
