T-Mobile USA Inc said on Wednesday it will begin selling its new 3G-enabled Dash smartphone in July, yet another entry in the hotly contested mobile phone segment.
T-Mobile said the Wi-Fi-enabled Dash 3G was designed by HTC, runs on Microsoft's Windows Mobile and features a full QWERTY keyboard.
The company said pricing was not yet available.
T-Mobile is a unit of Deutsche Telekom.
Research in Motion's BlackBerry and Apple Inc's iPhone dominate the high-end smartphone market, while Palm Inc's just-released Pre has also seen strong demand.
