Make sure there's enough room on your phone's SD card.I've got my own that I built, with the programs on it that I generally use, but the easiest way to get one to experiment with is to download the live CD image from the Fedora web site. Prepare a Fedora ISO image that you'd like to boot from.Here's what to do to get your phone set up for booting. For bonus marks, you can set your phone up to read the encrypted image and get access to your documents directly from your phone.
