Can’t get? iPhone SDK 3.3 with xCode 2.1.4 running inside Mac OSX 10.5.5, I have it running on VMware with Mac OSX 10.5.5 here’s how:
Download iPhone SDK 3.3 with xCode 2.1.4 from Apple here.
Then do the following:
Edit the version number from 10.5.5 to 10.5.7 inside the “SystemInfo.plist” file which is located here:
/System/Library/Core Services/SystemInfo.plist
Now you can install the latest iPhone SDK without any crappy messages coming up
