Sprint has just announced plans to offer the HTC Arrive, which will be this carrier's first device running Microsoft's operating system for smartphones.

As it will run Microsoft's new mobile OS, this smartphone will include a suite of communication, entertainment, and productivity software. This includes tie-ins to the Zune music store and Xbox Live.
More High-End Features
The HTC Arrive will have 3G, Wi-Fi b/g/n, Bluetooth 2.1, and a GPS receiver.
Other features are going to include a 5 megapixel rear-facing camera with LCD flash and a 1500 mAh battery.
Overall, this model is going to be 4.6 inches x 2.3 inches x 0.6 inches (118 x 59 x 16 mm). It will weigh 6.5 ounces (184 grams).
Coming Next Month
The HTC Arrive will be available beginning March 20, for $200 with a new two-year service agreement or eligible upgrade and after a $100 mail-in rebate.
Beginning today, customers can pre-order this model at any participating Sprint Store with the purchase of a $50 Sprint gift card.
A CDMA First
The Arrive will likely be the first device running Windows Phone 7 to be released by a carrier that uses CDMA . That's because Microsoft is just now adding support for this cellular-wireless networking standard to its operating system.
As it stands now, only GSM-based carriers like AT&T and T-Mobile can offer WP7 models.
