I just found this on Apple's Mac OS X Software page. It is a free development environment that claims to work well for the iPhone. Check it out here. I have also added this info to the Macrumors wiki on iPhone Applications. Other developers: Please post useful tools or info to the wiki so they can easily be found. As someone just starting in web development I would really appreciate the tips and tools you discover along the way. One more thing: does anyone know of a good app to easily create iphone like buttons and bars, or could someone point me to a good Photoshop tutorial on the matter? Thanks in advance.
