Bigboss has put up a guide on how to use winpwn (which is just really the window version of Pwnage). Its an awesome tool for us people who still don’t have a mac, unfortunately i still don’t have a macbook at the moment.

Anyway, I know most of you people out there are Windows user. Which makes this window version of Pwnage very useful. Below is how i pwned my iphone. Hope it helps. let me know incase you encountered any problem(s).

1. Download and Install the WinPwn application.
2. Make sure you are using the latest iTunes (version 7.7 and above)
3. Download Boot images for 3.9 and 4.6.
4. Get Your IPSW File Ready (1stGen iPhone and iPhone3G)
5. Open WinPwn and click the ‘Browse .ipsw’ button and then locate the IPSW file you are ‘pwning’ (from step 4).
6. After WinPwn recognizes the ipsw file, now click the ‘IPSW Builder’ button.
7. In the Applications tab click the box for Cydia (As of the moment I dont recommend ‘Installer’ simply because its still in beta), and then click the ‘YouTube Activation Fix’ box if you’re not on a official carrier network.
8. In the custom images tab. I suggest that you don’t select any checkboxes, if you want to use the iPhone default logos, etc.
9. You can just skip the custom payload tab (its not required).
10. In the Advance tab, check all boxes except for “No Wipe” and “Update bootloader.” Then select the proper boot imageswhich you downloaded earlier in step 2.
11. Just leave the root partition size to 500MB. (almost there ^_^)
12. Click the ‘build .ipsw’ button at the bottom. Save your “new” custom IPSW file anywhere you want (just dont forget where you saved it ofcourse).
13. After it creates your custom firmware it is time to Pwn iTunes. Click the ‘iPwner’ button and you should see an alert message saying ‘iTunes has been Pwned.’
14. Close WinPwn. Then put your iPhone/iPod Touch into DFU mode. Click here if you need help with DFU mode.
15. Now open iTunes, hold the ‘Shift’ key on your keyboard and then left click on the ‘Restore’ button in iTunes.
16. Browse and select your custom firmware. Then just let iTunes do it’s thing. after a minute or two you should see a dialog box telling you that iTunes just restarted your device.
17. Once your iPhone/iPod Touch restarts, you should see both the App Store and the Cydia icons.

note: currently Winpwn/Pwnage can only “jailbreak” iPhone3G (yet!). In other words, it still can’t activate iPhone3G. But as for the 1st gen iPhones, it can do both jailbreak and activate (here in the philippines, active is also known as unlock or open-line)
