Well, you are in luck, as WireFly.com is giving out 5 Android phones of your choice, including the EVO 4G, for comparing an Android phone to the iPhone, specifically, the ways the former can beat the latter.
The contest ends June 28th, when 5 most creative answers, as decided by the in-house judges, win. Unfortunately, it seems like only US residents can participate (thanks bsu).
There is public voting visible, but it doesn't affect the results - everyone is downvoting everything anyway in hopes of winning (though impacting nothing). Oh, human greed.
