We now have just 6 days until the start of SYS-CON's iPhone Developer Summit in New York's Roosevelt Hotel. During the now two-day event, there will be nine presenters as well as exhibitors such as Sybase.

Now for the next two presenters on my list:

Combining REST and Context for Killer iPhone Apps - Jason Christensen - Proprietor, jasonc411.com

With the advent of the multimodal nature of iPhone, it's possible to be connected anywhere and everywhere. But did you know that it's possible for your iPhone to provide context to RESTFUL web services to create the next generation of killer applications. We will look at using web services, cloud computing, and the sensors on the iPhone to create applications that exceed what could previously be done on mobile devices. With this architecture, the sky is truly the limit on the capabilities you can provide to the users of your application. We will create an application that can use RESTFUL web services in combination with the GPS sensor on the iPhone to create a context-aware chat client.
