Need an affordable smartphone with QWERTY keyboard? PhoneMag has done a hands on video with initial impression on the new T-Mobile Dash 3G, which is also called HTC Snap in other regions. Compare to the Dash 3G’s predecessor, the Dash 3G has a trackball at the middle  instead of the 4-way navigation keys. Check out the hands on video here or proceed to PhoneMag for the initial impression. A full review will be posted on the site soon.
