HTC-Supersonic-Sprint-WiMAX-AndroidAs it turns out, the HTC passion wasn’t the Android twin of the HTC HD2, but rather, was Google’s first mobile phone offering, the Nexus One. This leaked HTC Supersonic, however, looks to fit the part perfectly with its similarly-sized 4.3-inch touchscreen. The Supersonic, however, improves on what the HD2 first introduced into the market last year with a better AMOLED display. It also features a 5-megapixel autofocus camera, 1GB ROM, WiMax support, and a 1GHz Snapdragon processor under the hood. It’s loaded with Android 2.1, the only other phone we know of so far to run on the latest version of Android apart from the Nexus One, complete with HTC's Sense UI overlay.

Sprint is expected to launch the HTC Supersonic this coming March though price is still yet to be known. With the HTC HD2 headed for T-Mobile debut in the US this spring, the HTC Supersonic should serve as a nice alternative for Sprint especially for those who prefer the Android OS over Microsoft’s Windows Mobile platform.
