Google has moved into the hardware market and launched its widely anticipated first mobile phone, which will be available in the UK through Vodafone.
The Nexus One is expected to be a rival to the iPhone and will run on Android 2.1, software designed by the internet giant.
Android allows users to speak text into any field via a voice-enabled keyboard, and the phone also has a 3D photo gallery.
The phone is available to buy from today from Google's web store and via T-Mobile in the US. It will soon be available from more operators, including Verizon Wireless in the US and Vodafone in Europe.
Google says the Nexus One is "the first in what we expect to be a series of products which we will bring to market".
Google says it can ship the phone to the UK unlocked, allowing it to be used with a sim card on any network. It said the phone will be available on contract with Vodafone "in the near future".
