I wanted to have a go at developing an iPhone app without having to go out and buy a Mac so I managed to setup a Hackintosh on my Toshiba Protege m200. Below is how to do it. Having set everything up I found when rebooting for the 2nd time that I lost network conectivity so it’s best to download all your apps like Firefox after you’ve installed the iPhone SDK and before you shutdown or restart the computer. I got most of this information from this forum post. I haven’t been able to get an application working on an iPhone so I think this setup is only useful when targetting the simulator.
