WinPwn successfully jailbreaks iPhone 3G for Windows

Earlier this week, the iPhone Dev Team released WinPwn 2.0, a tool that allows Windows users to jailbreak iPhone 3G units. However the initial release was affected by an issue that caused the Ipwner component to crash. A new version,, has now been released, resolving this and other issues.

Jailbreaking allows full read/write filesystem access and the installation of unofficial third party applications.

Notes accompanying this release:

  • You must do a full uninstall of winpwn before installing the new version
  • Make sure you have the latest version of iTunes ( Currently 7.7)
  • WinPwn uses 300MB of ram at peak due to the ipsw being extracted in memory
  • You must first click browse and load an IPSW to use WinPwn
  • For 2.0 only the *5A347_Restore.ipsw files are valid. The 345 image will not work
  • If you see "Failed to load image catalog/payload catalog", ignore it
  • If you already have service with AT&T do not activate or install Youtube Fix

The new release and usage instructions are available from this download link.
