Google is expected to ring in the new year by unveiling its own smartphone on Tuesday, the Nexus One, in a bid to expand its powerful Web brand in the booming mobile arena.
The Internet search and advertising giant has already gained a foothold in the market with its Android mobile operating system, featured in a number of phones starting with T-Mobile's G1 in October 2008 and more recently with the Droid from Motorola.
But the Nexus One, designed by Taiwanese handset maker HTC, represents a significant departure in that Google is expected to sell the Google-branded phone directly to consumers who will not be tied to any one telecom carrier.
Apple's popular iPhone, for example, is available exclusively in the United States through AT&T, but buyers of the "Google phone" will reportedly have their choice of wireless carriers.
Technology blog Gizmodo, citing leaked documents, said the Nexus One will cost 530 dollars "unlocked" - meaning it isn't tied to a specific carrier - or 180 dollars with a two-year service agreement with T-Mobile, a subsidiary of Germany's Deutsche Telekom AG.
Google has been coy about any plans to jump headfirst into the fast-growing smartphone market, dropping hints but not confirming its intentions outright.
