WinPwn 2.0.0.3 successfully jailbreaks iPhone 3G for Windows
Posted 25 July 2008 @ 3pm in Guides/How-Tos, News
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, 2.0.0.3, 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.

I tried out the last version 2.0.0.2 and everything worked as planned until I delivered the payload to my ipod touch. Then Itunes gave me error messages and my ipod touch was unresponsive. I encountered this twice. I was able to recover my ipod both times but I’ve read comment after comment on the winpwn site from people who weren’t so lucky. This is certainly nowhere as easy as the original pwnage tool and should be used with caution.

Winpwn was not created or supported by the iphone-dev team..
http://blog.iphone-dev.org/
They created Pwnage Tool 2.0 , a Mac only tool to unlock/jailbreak a iphone with the new 2.0 firmware. They then released the source code, which cmw then used to make Winpwn.
I’m not trying to taki away from what either did, but we need to recognize the fact that the dev team slaved for a week and two days to get us a way to unlock the iphone 2.0 firmware… cmw thankfully ported it to window$ for us none mac users…
