The iPhone app store is undoubtedly the greatest market for mobile applications. It has revolutionized how cellphone companies and software developers provide applications to their mobile devices, by making it worlds easier for users to buy and download mobile applications.

There have been countless stories of individual app developers earning over $200,000 in months, and software giants such as EA and Gameloft have been rushing to get more apps out for the iPhone. But this raises the question, is the app store all that good?

Well investors seem to think the app store is a make of break market for software developers. Vonage’s stock skyrocket 20% today after Apple accepted their iPhone application into the App Store.

Vonage has been a struggling VoIP service provider for many months, and investors believe that their iPhone app can revive their business. A 20% rise in a companies value means that investors think the iPhone App Store will make Vonage rich, because it has made many other people rich as well.
