Playstation 3 jailbreak?

I found an old playstation 3 on the bulky waste and it actually works.

Can one play the PS3 "hack" or jailbreak and thereby play all Ps3 games or ps2 games?

Does that have any disadvantages?

Have a look on eBay / classified ads, there many modders offer their jail breaks, depending on the modder then cost 20-50 euro, depending on which you have more or less features, I got a completely new jailbreak PS3 there for 150 euro and I'm totally satisfied with it, it has several programs written by the modder that I find very useful and make it easier to use, for example a modchanger that makes installing cheaters around the world easier and keeps the usual jailbreak programs.

Okay, can you get banned quickly? Do you also play online?

What is banned, the games on the PS3 are no longer supported by the publisher anyway, so you won't get a ban there anymore, but each PS3 has an ISID that allows you to play online, so to speak, your identification number, which is every 2-5 months automatically banned so that you can no longer log in to the online service and you can't create new accounts either, you first have to buy a new ISID, which also costs about 5-10 euro on eBay, which you then have to use a tool that is also used for jailbreaking installed, change. Whether you spend 9 euro each month to be able to play PS4 online because of PS + or whether you buy a new ISID every 2-5 months for 5 euro doesn't matter much, but I would still stay with the PS4, have the JB Console has not been used for a long time.
