Microsoft's App Guy has quite a job on his baby-soft hands: to boost Windows Phone 7's numerically-challenged Marketplace by encouraging developers to port apps across from other platforms. The little fellow helped iPhone devs out a couple of months ago with an API mapping tool to make it easier to translate iPhone APIs to WP7 code. Now he's extended the mapping tool to work with Android APIs too, and backed it up with a 90-page white paper and a promise to get more involved in developer forums. Will the App Guy's efforts unleash a flood of new apps for Windows Phone? We don't know, but we dig his shorts.
