This Wrox Blox will help you create a simple RSS feed widget to run on your iPhone (or iPod Touch) using Dashcode. After a brief tour of Dashcode’s capabilities, you’ll get right to the task of creating the widget. You will choose a template, provide an RSS feed URL, set customizable attributes, change the UI of your widget, design a homescreen icon for your widget, test your widget and upload your code to a server. In just about an hour’s worth of work, you’ll be running a Dashcode-created widget on your iPhone.   After spending this time inside Dashcode, you should be able to use the other templates available in Dashcode to create other useful Web tools.

For example, you can use the Custom template to create completely new tools that integrate Google search functions. You can add Ajax and even server-side code to your widgets, and integrate with third-party APIs (like Flickr) to provide users with an even richer experience.
