How to Jailbreak your Iphone 3G Version 3.1.2

This is a description how I did it and worked for me.

Disclaimer Important: Do this step by step description at your own risk. Be aware that you you will loose your guarantee in case of failure.

  1. You need to make sure your iPhone is up to date (Version 3.1.2)
  2. Get Blackra1n
  3. [Ctrl+Alt Esc] Open Task Manager
    End Processes [iTunes.exe/iTunesHelper.exe/iPodService.exe]
  4. Connect your iPhone with the USB Cable and run blackra1n
    The first time it didn’t work for me. I always got just a black screen instead of the wallpaper picture. After I made sure my firewall is switched off and I changed the USB Port it worked like a charm. (Here a link with a more detail description for this step: blackra1n)
  5. After a reboot you should have a blackra1n icon (waterdrop)
  6. Open it
  7. Choose a Package Installer [I choosed Cydia] and if you want to use it with another phone carrier you can choose sn0w as well then click on Install
  8. Open Cydia
  9. Do all package updates
