A guide on how to put any version of iPhone or iPod Touch firmware in Device Firmware Update (DFU) Mode. This shows how to do it the way that Pwnage Tool shows you after you have created a custom firmware file. I am aware that there are other ways to put your device in DFU Mode but this is the way that I find easiest. To make/edit this video I used Keynote (Mac only application) and iMovie HD (2006). The song is Sandstorm by Darude.
