Greetings Apple Developers,

Thanks for your help!

I am an Apple-noob who recently acquired a PowerBook G4 with a PowerPC processor running OS X Leopard 10.5.5. I would like to develop iPhone applications on this system, but I know the SDK is only officially supported on Intel-based Macs. I found this tutorial but it is a year old and not sure if it applies to the current SDK Build 9M2621a (iPhone OS 2.2.1):
Surprise, iPhone SDK also works on PowerPC Macs | iPhone Atlas - CNET Reviews

I followed the tutorial anyway to get the SDK on the system, but I'm having trouble accessing the framework executables. Here's a sample of the error I'm getting and why I don't think my SDK installation worked:

"/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.2.1.sdk/System/Library/Frameworks/Foundation.framework/Foundation ; exit;
-bash: /Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.2.1.sdk/System/Library/Frameworks/Foundation.framework/Foundation: Bad CPU type in executable

If this is not possible, is there any way to do it with Windows XP service pack 3 or Vista Business? I'm looking for any alternative to having to purchase a new computer. If I have to though, would anyone like to sell me an Intel-based Mac?
