ps3 jb each time ?

how does it work ? if i buy usb jb for ps3 should i press power+eject each time i power my PS3 ? or only for the first time ? or its 1 time jailbreaking like iphone jailbreak ?
google answerd me
The jailbreak mode doesn’t survive a restart or a power off. So as you said, you need to perform the jailbreak every time you turn off or restart your PS3. You could in theory just leave it on all the time
wait a few weeks and there will (most likely) be a slightly modified firmware or similar that will make the use of psjb a one-time thing…
Answer #1
You’ve basically answered the question yourself. No one in history as of yet has made any custom firmware for PS3.
Efuses should make it quite challenging.
Power on and Eject, maybe for a while.
Answer #2
also you have to remove the power lead(slim model) or switch off at back (fat model) everytime you want to jailbreak your ps3
