I borrowed my PS3 to my GF for a few days and she managed to update to 3.6. I really don't know how she did it, because there were further updates available.
For me it's not a real problem, I wanted to erase the jailbreak anyway but now I got the problem that I can't excecute any Homebrews to delete the Log Files. Is there any way to do that on 3.6? I got a Bumblebee(AT90USB162) if that is helpful...
