Documents that appear to show the successor to the T-Mobile Shadow have become public on the FCC web site. The HTC-made device is very similar to the original Shadow, with the main differences being Windows Mobile 6.1, a faster processor, and a more rounded design. The draft user manual also lists separate battery life times for GSM and UMA, indicating the phone may support T-Mobile’s UMA-based Unlimited HotSpot Calling service. The documents show nearly identical features, including 2.6-inch QVGA display, spinning scroll wheel, slide-out 20-key text keyboard, 2 megapixel camera, Wi-Fi, microSD memory card slot, and quad-band GSM/EDGE. No information is available on a release date.
