It's time for a T-Mobile Windows Phone battle!  Aaron throws the Nokia Lumia 710 and the HTC Radar 4G into the ring.  The Lumia 710 offers a 1.4 GHz processor, 3.7-inch display with Nokia's ClearBlack technology, 5-megapixel camera with 720p HD video recording, a 1,300 mAh battery, and Windows Phone 7.5.  HTC's Radar 4G packs a 1 GHz processor along with a 3.8-inch display, 5-megapixel camera with 720p video recording, a front-facing camera, 1,520 mAh battery, and Windows Phone 7.5.  They're both "4G" (HSPA+) devices, and they're both available now at T-Mobile.

On one hand, you get Nokia Drive and a faster processor with the Lumia 710, but you get the front-facing camera, bigger battery, and metal build with the Radar 4G.  Which one offers the best package overall?  Part 2 of 2.
