    So, I downloaded the new PwnageTool and the bundles by msftguy. Ive created like 5 different Custom firmware packages but I cant get my phone to restore through it. I tried recovery mode, dfu mode, downgrading and then restoring. Nothing works. It starts the restore process, it says "Preparing phone for restore" and it just hangs there. Can someone who has jailbroken their iPhone 3GS on iOS 4 walk me through it. What am I doing wrong. I tried on two different computers, a Mac and a PC running Windows 7.

    You have to be on 3.1.3 jailbroken and update to the custom 4.0 firmware.

    I think you have to be in Recovery Mode for the update.

    Since it's the 3G you must also have an older model to jailbreak using pwnage tool. If you're iPhone was manufactured after September you can't use pwnage tool.

    It has to be an old bootrom 3G . Go check your model number and make sure it's MB.
