Sony Ericsson has released details and a video of its upcoming Xperia X10 smartphone based on Google's Android operating system.

The X10, which had been code-named Rachel, has a 1GHz Snapdragon processor, which should make this one of the fastest Android phones yet. The phone will sport version 1.6 of Android--aka Donut--and it will run applications from the Android Market and Sony Ericsson's PlayNow arena. The device will also feature an 8-megapixel camera, with autofocus and an LED photo light.

Expect to see the Xperia X10 in stores in the first quarter of 2010. Meanwhile, here's a video that Sony Ericsson posted Monday.
