Why do you think there are thousands of developers flourishing and making applications for Apple Inc.’s smartphone? Some offer their applications for free while others require you to pay (application starts from 99 cents to $999).

Aside from that, developers also don’t have an assurance whether their application will be rejected or not by the Apple Inc. especially now that the company seems to have hidden policies regarding the applications that will be entertained on the App Store.

But with this news, maybe the developers will be more inspired to do applications for the iPhone. Recently, Raven Zachary, one of the founders of iPhoneDevCamp, found out that his former colleague earned thousands of dollars through his application for the iPhone. Steve Demeter, the developer of the game called Trism, reported that he earned as much as 250 thousand US dollars since the debut of the App Store (July 11, 2008).

For those who do not know, Trism is a puzzle game worth $5 for every download. Trism features a touch and tilt game that resembles to the gameplay of other applications including Bejeweled and Tetris.
