GameStop's mobile plans became real Friday after the company started up a tablet test program to sell tablets online and in stores. Android tablets like Acer's Iconia Tab A100, ASUS' Eee Pad Transformer, and Samsung's Galaxy Tab 10.1 will be available in 200 of its stores. Each will have both access to Kongregate's Arcade app store as well as seven free games, including EA's mobile versions of Dead Space and Madden as well as Sega's Sonic CD.
