I've been trying to install winpwn 2.5 in windows 7 but it's not compatible. Winpwn is just compatible for winxp and below; and I don't have any computer or laptop that has a different Operating System. Any solution to solve my problem? The reason for that is I want to fix my Iphone.
If you install Windows Virtual PC you can install XP on the virtual PC and then install winpwn on that.
However, from the page:
And you may also need an XP license key, though there is an "XP Mode" download on that page as well.
