need some help with jb

[leeunwin]

ive bought a ps3 of a mate he has already jailbroken it and as been using it to play games of hard drive ect ect...

its got the ftp icon

and the open manager on


he asnt gave me the jb dongle as he was using his ipod to jailbreak it

what do i now need for me to beable to back up my games to hard drive do i need to buy a jb dongle as i guess that it needs to be always plugged into ps3

[leeunwin]

also if i buy a jb dongle i take it i will have to start from scratch and jailbreak the ps3?

what do i do about the ftp server and stuff already on the ps3?

one more question im thick

if i buy a new internal 2.5 hard drive and install this before doing jb ect.. will it cock all my firmware up im running 3.4.1 and dont want to update that for obviously reasons so if i bought a new hardrive would i need to update?
