Sprint could not provide specific battery life for the smartphone with 4G capability, but a company spokesman estimated the life to be more than five hours.

The phone runs Google's Android 2.1 operating system, and more than 35,000 apps will be available for the device. The device supports Adobe's Flash video platform, and will also able to play back 720p video on a external monitor via an HDMI (high-definition multimedia interface) cable. Small screens are not usually designed to play high-definition video.

Sprint currently offers 4G connectivity in 32 U.S. cities, and covers 41 million people. By the end of 2010 the company said it will cover 120 million people. But where 4G connectivity isn't available, the smartphone will switch to the 3G network.
