2. Click the Advanced Mode button and then select the iPhone 3G. Finally, click on the blue arrow to continue.
3. Then will begin the search for the original 4.1 firmware inside your computer. If you have more firmware stored in the Mac, be sure to select the one corresponding to the 4.1 version, then click on the arrow to continue.
