New to iphone....

I am trying to figure out how to jailbreak my phone. It is a 3G and I am running a MAC OS X version 10.6.4. If anyone could walk me through the process I wool be grateful.

Check to see what firmware and baseband (modem firmware) the phone is running (Settings/General/About), then look here:
iPhone & iTouch Jailbreak / Unlock Matrix | jailbreakmatrix.com

The chart will tell you if you can jailbreak and what software to use.
