The iPhone Dev Team managed to release two iPhone Pwnage Tools so far, one for Macs and one for Windows. The Pwnage Tool 2.0 for Macs had a couple of bugs which were fixed in an immediate follow up release of the Pwnage Tool 2.0.1.

The Dev Team has released the WinPwn 2.0 too earlier this week. This way Windows users can jailbreak their iPhone 3G handsets. Apparently the first version had a few bugs too so an updated version is available. Should you want to jailbreak your phone, make sure you download the new version, the WinPwn 2.0.0.3.

Here are a few instructions you might need in order to use it:

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
