I currently have an iPod Touch 2G model MC, running iOS 4.2.1 which cannot be downgraded AFAIK, but I need to build an iOS 3.0 app
So, it would help to have an Xcode with both an iOS 4.2.1 compatible SDK and iOS Simulator 3.0 too
Any help is appreciated
iPhone SDK 3.2 Final with Xcode 3.2.2 for Snow Leopard (10.6.0) has iOS Simulator 3.0 built-in
Xcode 3.2.6 and iOS SDK 4.3 GM Seed for Snow Leopard (10.6.6) can be installed, then using the former DMG it could be installed iOS Simulator 3.0 with these packages:
“/Volumes/iPhone SDK/Packages/iPhoneSDK3_0.pkg”
“/Volumes/iPhone SDK/Packages/iPhoneSimulatorSDK3_0.pkg”
