Your post inspired me to pull my old PS3 Slim off the shelf and give it a shot. Fortunately it is one of the ones capable of custom firmware. I successfully jailbroke it and am now running custom firmware, next I just have to figure out how to do anything useful with it, lol.
Yeah, and this game is 100% worth the ten bucks they’re asking for. I already own it on Steam (where it cost $20 when I got back at the beginning of the year), and will happily pay another $10 to have it on my phone too.
