How do I jailbreak my iPhone 3G 4.0 IOS?

I've never jailbreak my iPhone before. I upgraded my OS 4.0 to the release date. What programs I can use to jailbreak my iphone? plz help! I want free apps and Cydia! Also, how I can downgrade my iPhone I am using a new computer, I just do. ??

Redsn0w to jailbreak and unlock Ultrasn0w. Please note that these hacks completely suck. The phone is idle more than you can imagine, and everything that hangs all the time. All applications that I downloaded from Cydia bricked my phone. I'm glad I did the release, but I'm trying to restore everything and wait for something better to develop.
