T-Mobile has just announced their first 4G capable Windows Phone and it’s running the new Windows Phone 7.5 operating system. The HTC Radar 4G has an aluminum unibody design, 3.8″ LCD touch screen, 1Ghz Snapdragon processor, 5 Megapixel camera with flash on the back and a front-facing camera for video calls. Of course it also has all of the cool enhancements and new features found in Windows Phone 7.5. Unfortunately the battery is not removable, but hopefully it will last long enough to get through the day. The HTC Radar 4G is expected to be available in time for the holidays. UPDATE: The HTC Radar 4G on T-Mobile will have 8 Gb of storage space built in just like the European version.
