Punch sprint.com/arrive into your address bar and the above is what you shall find. Not a generic error marker but a URL-specific "coming soon" message that would seem to confirm the existence and indeed near-future arrival of the HTC Arrive. Beyond that bit of web sleuthing, we also have ourselves a proven tipster informing us that this will be a carrier-branded version of HTC's 7 Pro and confirming that it will be launched tomorrow. A tweet from Sprint earlier this week, intimated heavily that it's about to introduce a Windows Phone 7 handset on the 24th, which we surmised to mean exactly the long-awaited 7 Pro QWERTY slider. Already available in Europe, this device will serve as the first CDMA representative from the WP7 stable, meaning that you'll soon be able to Glance and Go on the Now Network of alliterative advertising slogans.
