Ok I downloaded the 2.1 firmware. Now what program will allow me to edit it? I downloaded the new winpwn 2.5 beta and it say it will only do 2.0, 2.0.1, 2.0.2. None of these are 2.2.
Winpwn 3.0 hasn't been released yet. This is the Windows version that will enable you to create a custom 2.1 firmware. Until then, you might want to go to
Then, you can use iTunes 8.0 and install the new 2.1. After you have done this, install Quickpwn and run it. Then you can go on about your business with your jailbroken iPhone.
