Time to get to work: A week after announcing its mobile applications platform, Google has launched a $10 million contest for developers that come up with the best mobile software in areas like social networking, media sharing, gaming, location-based services and news and information. The 50 most promising entries received by March 3 will each get a $25,000 award. During the next stage, these winners will be eligible for ten more prizes of $100,000, and another ten at $275,000.
