Well, that was quick, wasn't it? After US Cellular recently announced its upcoming smartphone lineup, its very first Windows Phone -- an HTC model -- was ready for a summer launch with or without an official name. We now know the mystery device is the CDMA version of the HTC 7 Pro, a phone that Sprint lovers know better as the Arrive. Available tomorrow for $200 with contract after $100 mail-in rebate, the full tilt-up QWERTY slider with 5 megapixel shooter and 16GB internal storage is a bit on the spendy side. Oh, and it requires a monthly data plan. Did you just hear that noise? That was the sound of your wallet trying to hide from you. Full press release after the break.
