To get started developing for iPhone, there is two approaches : link your PC to your iPhone and start testing directly, or simply use a similator. iPhoney is the first iPhone similator, and I guess this approach is much more easier. iPhone Browser Simulator provides an iPhone sized web view with which to test your iPhone targetted apps, all in a pretty iPhone-inspired package. iPhoney is available for MacOS only but now that open sourced under GPL, probably more systems will be supported.

iPhoney 1.1 new features include :

• Zoom out to see how your current pages might look while zoomed out on iPhone.
• Turn off plug-ins (including Flash, but note that they all turn off (including QuickTime).
• Specify a custom user agent string.
• Automatic updates with Sparkle, so you’ll always know if there’s a new version.
• And of course, open source code so you can contribute to iPhoney’s rapid development.
