I have addressed this in a number of threads but I think it needs it own. [MBM] the guy would reverse engineered an sbf file to flash SPRecovery also made it possible to flash sbf files in Linux. Instructions and needed files can be found on his blog here OPTICALDELUSION: sbf_flash I don't currently run Linux on any of my computer so I cant be of much help with this but I have talked to people that have done it and it does work. Just wanted to show people there is another option other than just windows for rooting the droid. If you run Mac Os then I cant help you though.
