Anyone that has doubted the profitability of selling apps in the iTunes App Store can have their doubts put to rest. In fact, Trism, which we reviewed a few months back here on iPhone Buzz has crossed the $250,000 income mark.

The developer of Trism, Steve Demeter let the news out on his income at a conference. The app did receive some press coverage prior to its release at the launch of the App Store, however, this is still evidence of just how popular a platform the iPhone can be for games.

Since it's release on July 11, Trism has sold over 71,000 copies. That clocks in at an average of 1,200 copies a day! You can currently purchase Trism from the App Store for $4.99.
