I can use mono in Windows 7 for developing applications for iPhone. What开发者_如何学Python I have to install?

Here is the documentation for the installation process: http://monotouch.net/Documentation/Installation

It is not possible to run this on Windows, you need MacOS.

However, some parts (Business layer...) could be developed independently on a Windows machine.

No, you can't. MonoTouch (the tools and libraries on top of Mono that can be used to build iPhone apps) depends on the iPhone SDK, which runs on Mac OS X only.
