@underball , one weird thing I've notice when going from Iris to multiMAN. The sparkles in multiMAN screensaver start to twinkle like a million times a second. I have to reboot the PS3 and not load Iris for that session, so that multiMAN will be back to normal.
I think there is a payload problem between the two managers. But this new report above, seems to be between Showtime and Iris--but perhaps he used the standalone version of Showtime--the one that is associated with multiMAN, that when you exit Showtime, it takes you to multiMAN?
And who knows what other issues can occur when firmware gets corrupted. Having to reinstall your CFW can be something very serious and not for the noob that is just getting started. :)
So when I read some people say, don't use multiMAN, use Iris and blah blah blah. They show their ignorance, because Iris is not yet ready for prime-time. And there are no guarantees it will improve or not. So be careful!!!
