On Tuesday, Google is expected to unveil its first ever smartphone, the Nexus One, which will mark the search engine giant's expansion into the much lucrative smartphones market.

The search engine and internet giant already has a strong foothold in the sector with its Android mobile operating system, which has become one of the strongest OS platforms used by some of the most popular devices all over the world.

The Nexus One has reportedly been designed by HTC, the Taiwanese manufacturer which has already introduced devices with an Android platform.

It has been rumored that the Nexus one would cost $530 unlocked, i.e., without any carrier contracts, and currently, would be available with an AT&T two year contract.

Google has been very quiet about the device, and it is expected that it will be one of the most popular devices once released.

On January 5, Google has scheduled a press event, which everyone is expecting will be the platform to debut its phone, and all eyes and ears are now on the event.
