Aptana really is the premier JavaScript IDE out there with a variety of support for JavaScript, Ajax, DOM, Adobe Air and now the iPhone. Yep, Aptana has just released a beta of their new iPhone Eclipse plugin which will help you in building apps to work within the confines of the iPhone.

The cool thing is that the plugin will allow you to preview what your app will look like in a simulated iPhone page. Very cool.
