What are you going on about??
a modded usb?? wtf.
the only thing a modded usb.. or else know as a development board.. is used to jailbreak the ps3.
I personally took the free way by using my ipod touch 1g and jailbroke my ps3 via that way.
Once u jailbreak it.. you simplily add ps3ftp pkg. and backupmanager to a NORMAL FUKN USB and go to install pkgs and install them. YOU DONT ADD THEM TO THE IPOD/DEVELOPBOARD!
What do u mean it comes with the backup manager??? you download the manager... the same as the ps3ftp pkg and add to usb to install AFTER you have jailbrokn your ps3.
You obviously havent jailbroken your ps3.
*flame* nice come back.. just copying what the first person says. Love the childish response
