Apple announced today during WWDC that developers will be able to develop applications for the iPhone.

Developers can create Web 2.0 applications which look and behave just like the applications built into iPhone, and which can seamlessly access iPhone’s services, including making a phone call, sending an email and displaying a location in Google Maps. Third-party applications created using Web 2.0 standards can extend iPhone’s capabilities without compromising its reliability or security.

“Developers and users alike are going to be very surprised and pleased at how great these applications look and work on iPhone,” said Steve Jobs, Apple’s CEO. “Our innovative approach, using Web 2.0-based standards, lets developers create amazing new applications while keeping the iPhone secure and reliable.”
