Google is expected to announce its mobile phone plans Monday. For about two years now people have been speculating about Google working on a mobile phone or mobile operating system. According to the Wall Street Journal, Google has been in talks with T-Mobile and Sprint to offer cell phones powered by Google and it might partner with HTC, a Taiwanese phonemaker, for a Google cell phone. The search engine company is also going to bid in a wireless spectrum auction in order to become a wireless operator if it wins. Mobile web surfing is increasing sharply and the market gets more valuable every day with new mobile advertising services, better hardware and improved mobile web browsers. It would only be logical if Google tried to expand into mobile surfing in order to consolidate its Internet monopoly.

GOOG‘s stock is at $711.25 today, making investors happy who have gained about 55% or $250 per share since the beginning of this year. Many analysts are still rating GOOG as a strong buy. Now, Google joined forces with MySpace for the collaboration on OpenSocial, a platform for the development of social networking applications. This strategic move could possibly turn out to be a partial success against Microsoft/Facebook. We’ll see. At the very least, Google’s stock keeps climbing and neither Microsoft nor Yahoo nor any other company has found a way to rival Google, yet.
