The highly anticipated launch of the smartphone by the search giant was unveiled at Google headquarters in San Francisco yesterday.
The phone is Google's first official mobile phone device, built by manufacturer HTC, since it acquired mobile operating system company Android in 2005.
Vodafone will be Google's first UK operator partner to offer the phone but on a non-exclusive basis. The phone is set to go on sale in the US, Singapore and Hong Kong initially and will later be rolled out in the UK.
The touch screen, sleek phone will cost $179.00 (£111) for a two-year contract with T-Mobile USA. Nexus One can also be purchased for around $529 (£324) on its own. Verizon Wireless in the US will plan to offer services to customers in the near future.
Like the iPhone, Android offers fully integrated web-browsing and video applications with a five megapixel camera. The phone will offer 18,000 apps and unlike the iPhone, Nexus One allows multiple use of apps at the same time.
Users will also be able access Google maps, emails and aggregated contacts. A voice enabled keyboard has also been embedded for speaking text messages, emails, tweets and Facebook updates.
