- Download the 2.1 firmware for iPhone 3G from the iPhone Downloads section and save it to your desktop
- Install iTunes 8
- Update your iPhone to firmware 2.1 with iTunes and make sure it is activated
- Uninstall iTunes 8
- Uninstall Apple Mobile Device Support (From Add/Remove Programs in Control Panel)
- Install itunes v7.7. – you can find it here
- Download QuickPwn with the correct 2.1 bundle inside it here
- Run QuickPwn. Select the iPhone 3G 2.1 firmware that you downloaded in Step 1
- Select at least Cydia. You may also select Installer
- Once finished, your iPhone will reboot, which may take a few minutes. Cydia and Installer will not be visible on your springboard. Don’t panik! This is ok.
- Download TotalCommander and t-pot addon
- Install TotalCommander and in the left pane navigate to T-PoT.1.1.zip and click on it. It will install t-pot automatically

- Use Totalcommander to install the patched mobileinstallation file to /System/Library/PrivateFrameWorks/MobileInstallation.framework. Click on the dropdown box [-\-] top left and select network neighborhood then t-pot. Remember to back up your original mobileinstallation first!
- Still in TotalCommander delete /private/var/mobile/Library/Caches/com.apple.mobile.installation.plist
- Reboot your iPhone
- Done!
This is not the most straightforward method to jailbreak your iPhone 3G but it is the only one so far! As usual, use it at your own risks…
