You can unsolder and use it on other ps3s. You just use the Samsung 10.28 update.bin.
It is the flasher that gets married to the first PS3 you use.
The linker is just an alternative to the clip. It does the same thing as the clip. Except you solder all the wires yourself.
I can see why you would want to leave it in the PS3 though. Those solder points are so tiny, I couldn't imagine having to solder and unsolder it everytime. LOL. I guess I'm just spoiled with the clip.
The clip does get worn though. I have broke one, and luckily I had already ordered and received the nor clip suit. I need to order another clip now, so I have a backup.
But yeah, I got my 3k Limited edition in Dec. 2011, from coolgadgetgifts
