Just thought I'd warn people. I tried to run the Netflix app on my PS3 without running the new update (3.55?), and it didn't work out so well. After about 3 warnings about having to log into PSN, which I couldn't do, of course, the whole machine just locked up with the Netflix app in the background and the PSN login in front. It wouldn't respond at all, and I had to perform a hard reboot.
