The Wired How-To Wiki provides some handy hints for gaming on your mobile phone, the regular old un-smart kind. Covered are searching for games, downloading, and playing. Because the site is a Wiki, you can also contribute your 2 cents worth, if you have a tip or two that you'd like to share. Just goes to show that you don't have to drop $600 to have a good time...er, that just didn't come out right but you know what I'm getting at. As for me, I'll find my games in the Android Marketplace.
