Sprint just confirmed the rumor about the HTC 7 Pro and announced that the HTC Arrive will launch on 20 March. The good news is that this new WP7 device will launch with the latest software that includes copy and paste support.
The HTC Arrive will launch with 16GB of internal memory, which is the largest capacity found in WP7 devices natively. You will be able to purchase it for $199.99 with a two-year agreement and after a $100 mail-in rebate (can we please do away with these?). You can actually pre-order one today with the purchase of a $50 Sprint gift card and you will receive an appointment to pick up an HTC Arrive.
The keyboard looks to be similar to the one found on the HTC Touch Pro 2, which was the best side slide QWERTY keyboard ever made, IMHO.
