Sprint is reading an ultimate Android smartphone that it hopes would draw attention to its network, a leak late Sunday hints. Nicknamed "Supersonic," the HTC device is expected to be similar in spirit to the HD2, including its very large 4.3-inch touchscreen. The Engadget contact notes it would run Android 2.1, however, and would be one of Sprint's first phones with WiMAX, beating other US carriers to having the first 4G phone in the country.
