First time Jailbreak

Hi all

This is my first time at posting on here and my first time if I can jail breaking. I am looking at buying an old PS3 to try to see if I can jailbreak etc. However, when going on the web I get mixed messages regarding whether I can do it.

The ps3 is a slim 160gb with model number Cech2504A. Is this jail breakable?

Unsure as to which firmware is on at present.

If so, which is best guide to use to jailbreak? What apps etc is best to use

Any help or advice would be greatly...​
