Geohot had a 3.21 with OtherOS as i remember. Don't know for sure if it was on a Phat or a Slim. I think it was a Phat because he needed a Phat to crack the PS3.
Now will it be possible to create a 3.41/3.50/3.55 pup with the OtherOS from 3.15 in it?
I know OtherOS still keeps it's slow and bad performance on higher FW's but just to show the world the scene can repair the removal fail from Sony (and notalgic reasons of-course ). It would be nice if I can update my Phat 3.15 to a higher OS without losing OtherOS.
and AsbestOS is the best way to go but with all the recent developments I don't know when we will see something useful. I think AsbestOS is based on payloads to load at the start and if we don't need to use the dongle in the future some trivial parts of AsbestOS have to be changed. Running Linux on top of the GameOS so it can make full use of the potential of the PS3 is almost the best I can think about for my PS3 (AmigaOS I would kill for (in a game that is ).

How nice is it to have a black box near your TV that can do everything you
