Mobile Complete, a 3-year old San Mateo-based startup that provides mobile application testing services, says it has raised a Series B investment led by Motorola Ventures. While the round size is officially undisclosed, it is rumored to be around $10 million. Previous investor Innovacom VC also participated in the round.

The company says it’s using the new funds to expand its service internationally and add more mobile handsets to its testing of roster of 300+ list of handsets. Check out the company’s virtual device-testing service called Deviceanywhere.com.
