Now you will have to select whether you’d like Cydia, Icy, or both installed on your phone. You have to install at least one of them. Make sure your choices are checked and press next. *It seems some people are having issues with Cydia crashing instantaneously after launching it. So it may be wise to select Icy. Both apps essentially serve the same purpose.
Next you will be connecting your iPhone 3G to your Mac. Once your device is connected, hold the power button until the “Slide to Power Off” appears - then slide to power it off. Press next.
redsn0w will not put your iPhone 3G into DFU mode. Be sure to follow the onscreen instructions exactly. Start by holding down the power button for 3 seconds.
Hold down both both the power button as well as the home button for 10 seconds.
Finally release the power button while continuing to hold the home button down until redsn0w detects your iPhone 3G.
The iPhone will now reboot once it is detected by redsn0w.
The application will now begin the process of uploading the new ramdisk.
Once this is complete you will be notified that the jailbreak process is complete. Click the Finish button. Even though redsn0w completed it’s process your iPhone will still be finishing up. This can take up to 5 minutes. Be patient, when it’s done you will have a jailbroken iPhone 3G with Cydia/Icy on the SpringBoard.
