I advise people to use this with EXTREME CAUTION. Since when you activate this hack, it disables USB charging, you're screwed if your phone's battery runs dead and you don't have an external battery charger (which i suspect most owners won't).
You should probably put out a note to use it only with = or > say 50% battery, and immediately restore a proper kernel upon successful execution of the exploit on the PS3.
Sounds like an awful lot of stuff to go thru to do this! I hope that whenever they release an iPhone/iPod port, it wont be this difficult! I doubt it would... hopefully just be a cydia package... hopefully soon we can find out!
Its not a command your looking for... you copy the files to the sd card itself... Connect the phone to the pc and copy the file boot.img to the sd card. and Copy psfreedom.ko to /data/ on root of device
