How to install iOS image (dmg file) from Dev Center? I downloaded an iPhone iOS dmg file from the iOS Dev Center, but don't know how to install it.

How do I load it on to my device?

I'm using iTunes 11 on Windows.
Files and applications in the iOS Dev Center are tools for developers working on iOS application development. As an OS X system is required to run Xcode and to install test apps on an iPhone, any supporting tools require OS X as well. You can't install them directly on iOS.
