A few weeks ago, we saw the HTC A9292 makes its debut on a leaked Sprint inventory list. Dubbed a WiMAX candybar, the A9292 is rumored to be the HTC Supersonic, an Android-powered beast with specs worthy of its codename. The Supersonic was tipped to include a 4.3-inch LCD display, Android 2.1 with Sense UI, WiMAX connectivity, a kickstand on the back like the Verizon Wireless Imagio, and, though Snapdragon is not confirmed, it is reportedly Snapdragon fast. The Supersonic’s software is reportedly still buggy so a launch date is assumed to be a little ways off. Though it’s a time frame that fits nicely with Clear’s projected 2H 2010 launch window for the first 4G-enabled smartphones to hit.
