I've gotten OSX 10.5.4 to work under VMWare.
Everything works, include XCode with iPhone SDK, Interface builder.. etc. It compiles and can also go through the iPhone Simulator. I haven't upload any apps to the iPhone yet though.. 'coz I need to learn how to program in Cocoa/Objective-C. (Anyone want to give me a helping hand?)
If interested, please follow the guide @

Cheers, gl all.
***This won't work on AMD system. If you have AMD, I urge not to hamper the dude with "why it doesn't work 'coz I have AMD".
