So that’s why HTC recently trademarked “Arrive”. The first CDMA Windows Phone 7 device will be the impressive HTC 7 Pro, which we reviewed in the European flavor. It features a slick slide-out keyboard with a tilting screen, and runs with 576MB of RAM, plus a 1GHz Snapdragon CPU. All the facts add up: if you go to Sprint.com/arrive, you’ll see a placeholder. Also, just this week Sprint was tweeting that on February 24, they’ll be releasing a new phone.
