I have successfully done this on my 1st gen 8gb iphone early Sunday morning. It is currently unlocked, jailbroken with App store and Cydia running 2.0 firmware using windows!! Well it’s still not available for Windows users officially, but what you can do is follow these instructions from Kinetic-X and NightCrow then load the pre-built custom firmware image. You will have to download the image from a *******. The details are able to be found here. You can get the 1.1.4 restore firmware image here. Step 1: Use WinPWN 1.0 To PWN Your 1.1.4 iPhone. If you need WinPWN Get it: http://www.winpwn.com/files/winpwn_18.104.22.168_RC1_Setup.zip Step 2: Install BootNeuter (Available Via Installer). Step 3: Run BootNeuter and have it Neuter your iphone Step 4: Make sure your iTunes version is at 7.7 Step 5: Grab a pre-created IPSW Made with PWNAGE 2.0 Mac. Step 6Please Register or Log in to view imagesut your phone into recovery or DFU mode. Note that some users report DFU works best while others are reporting normal recovery mode works best. If you have an error, try swapping modes and toggle between these two types of recovery until one works. Step 7: In iTunes Shif+Click the Restore button and find your custom IPSW Firmware file. Step 8: Wait for it to complete! ENJOY! Link credit goes to http://sleepers.net/news/2008/07/20/pwnage-option-for-windows-users/ Thank you guys!!
