In August we reported the first time that the iPhone App store is making independent developers quite happy with wades of cash each day.
Wired has a new success story about the guy behind the iPhone hit game Trism. Steve Demeter already made $250,000 with his $5 iPhone game in only two months. At this rate he would be multi-millionaire within a year.

The App Store makes it easy for anyone to find, purchase, and install new software. As the iPhone eco system grows every day, revenue for software developers will grow even further.

Of course the software needs to be done well to succeed on the App Store, but developers do not need to invest in marketing and distribution.
