How to uninstall OS4 and revert back to version 3.1.3

Wow! I just wrote a post asking for help about how to downgrade the OS on my iPhone 3G and it got deleted!

I understand that other people are asking the same questions but deleting them wont make the problem go away.

Does anyone know how to downgrade the iPhone OS from Version 4?

3G, iOS 4

It looks like a extortion to buy a new iPhone 4.
