The Nexus One is due to be unveiled today at Google's Californian HQ.

The phone is expected to cost a little over £300 in the UK for an unlocked version, or just over £100 with a two year contract from T-mobile, although so far, no details have been released about the phone's release outside the US.

Early reviews of the Nexus One have been fairly underwhelming, with most critics saying that it is no different to existing phones running the Google Android operating system such as the Droid from Motorola.

Details are sketchy but it has been confirmed that the phone contains a fast processor, camera, flash and accelerometer.
