Steve Jobs has met the expectations when he introduced the 3G iPhone on Monday, but the real revolution is just about to begin. And its name is AppStore.

On Monday at WWDC, Jobs has unveiled the first application for iPhone, but apparently thousand more will be ready on July 11, when AppStore will be officially available.

Jobs announced the AppStore back in March and it is a new application that lets users browse, search, purchase and wirelessly download third party applications directly onto their iPhone or iPod Touch.

Gene Munster, a Piper Jaffray analyst, has discovered that half of the twenty developers to whom he spoke at WWDC are ready to create new applications for iPhone and, of course, for iPod Touch.

In fact, it seems like Apple has learned some new things from the iPod experience. Its iconic multimedia player has generated a huge market of accessories from headphones to stereo speakers.

Now, with the 3G iPhone, Apple seems to follow the same pattern, but with the software platforms. As announced in March, every developer can submit their applications to the AppStore and Apple would retain 30 percent of all sales revenues.

With the AppStore, Apple will be able to generate revenues not only from selling the iPhone, but also by providing the applications.

The analysts have already started to make some forecasts and they concluded that by the end of 2009 the AppStore will generate between $150 million and $230 million in revenues for Apple.

Meanwhile, various companies have announced that they are developing iPhone versions of their software. For example. TomTom, the Dutch manufacturer of automotive navigation systems, announced a iPhone version of its software will be available through the AppStore.
