Yesterday, the WorldWideDeveloperConference (WWDC) started in San Francisco. Steve Jobs kicked off the event with his traditional keynote. After announcing Safari for Windows he came up with one last thing: How to write iPhone applications. And it’s easy: If your app runs in Safari, it will run on an iPhone, too. As a developer, you can access with your web 2.0 AJAX applications also iPhone functionalities like "making a phone call" or "sending an email". We’ll see what Apple will make accessible in detail.
