Four months after launching on Sprint under the moniker HTC Arrive, it looks like the HTC 7 Pro is making the rounds among smaller carriers: earlier this week it hit US Cellular, and starting today you can also pick one up through Cellular South for $199.99 with a two-year contract and a $50 mail-in rebate. To recap, the 7 Pro is a full tilt-up QWERTY slider with a 3.6-inch WVGA display, 1GHz Snapdragon processor, 5 megapixel camera, and 16GB of storage. So is it worth the $200? That all depends on how long you've been holding out for Microsoft's slick Metro UI -- the 7 Pro is, after all, the only WP7 device you can buy through Cellular South. Full press release after the break.
