I know most that use pwnage build the custom firmware on a Mac and then proceed through the DFU install on the MAC. How many of you out there have created the custom firmware on a friends MAC and then installed it via your PC? I've done this many times in the past and never had a problem, but now I'm hearing that it may be problematic with pwnage 4.1. Any real-life success or horror stories out there? If horror, is there a solution? Thanks to the forum.
