As expected, Samsung and T-Mobile have launched the Blast slider today, a phone that puts a big emphasis on messaging capabilities. The 1.3 megapixel camera and EDGE data aren't going to get any jaws dropping, but the SureType keypad (something Samsung has pulled off in the past), integrated support for popular email services like Gmail and Yahoo, and crazy color scheme just might. What's better, T-Mobile is charging the same rate for email sent and received on the T729 for the same price as text messages -- no data plan necessary (why haven't other carriers thought of this?). Other features include stereo Bluetooth, microSD slot, and -- naturally -- myFaves support. Look for it on store shelves any day now for $99 on a two-year contract.
