LG has announced its first cell phone based on Windows Phone 7, Microsoft's new handset operating system.

The Optimus 7 has a full-face 3.8-inch capacitive touchscreen (800 by 480 pixel resolution) covering most of the front of the phone. There are three buttons underneath the display, according to images released by the company.

LG says it has a 5-megapixel camera and can also record high-definition video in 720P mode. The phone also includes an accelerometer, proximity sensor, ambient light sensor and digital compass.

The phone also supports the DLNA (digital living network alliance) protocol, which allows for easy networking of consumer electronics devices. This means the phone should be able to access other DLNA devices, such as PCs, home servers and TVs to send or receive content.
