The 3.0 firmware was supposed to also finally allow screen cast functionality via miracast, see here:

I'm a bit disappointed to find that they seem to have restricted that feature to the new models. At least I haven't been able to find any way to switch on screen cast on my "old" Note 2 (bought this summer) after the update to v3.0.
Has anybody found a way to activate screen cast?
