Last year Apple had turned down Google voice application which resulted into public spat and prompted the U.S. Federal Communications Commission to request more information from the companies on the matter. Apple responded at the time that the Google Voice app had not been rejected, but that it was under review.
Recently, the competition between both these giants has increased further as both encroach into each other market. Google has entered the mobile market with the launch of Nexus One and has declared that it will soon be launching an operating system which will challenge Apple's Mac PCs.
Google Voice allows users to make cheap long-distance calls and to forward calls from a single phone number to multiple phones. Google already had a version of Google Voice available through mobile Web browsers. Amongst all these controversies, Google CEO Eric Schmidt had resigned from Apple's board of directors in August last year.
