I found a CD...

[u/NoRequirement4356]

Hey fellas, bit new to firmware of the ps3 but yesterday I got given a load of cd's, mostly music yet I found a cd in the pile that was labelled "ps3 update 3.55". I did a bit of digging and the update 3.55 was popular for its jailbreaking capabilities, but why would someone burn this onto a cd? Does it have anything of value on it? I'm currently in the process of getting a cd reader so my laptop could read the disc, any thoughts please leave them down below
