    Do the OPTION + RESTORE (On Mac) and pick the 3.0FW. Then it will give you an iTunes error (1015 or 1016). Download Quickpwn22-1. Once downloaded, connect your phone to your computer, open Quickpwn and there will be a small window that will prompt you to put your phone on a DFU mode (Press home and power button for 15 secs, let go of home button and still pressing the power button, do it for another3 secs). Then install Redsnow and install your 3.0FW

    Hope this helps...
