I downgraded to 4.2.0.89, and so far the bluetooth seems to be working ok. However, opera mini is crapping out constantly with java errors (even after changing application permissions), and I can't seem to minimize the dollars5 mediaplayer software anymore when streaming mp3's.

I use opera mini way more than the GPS. I'm gonna try upgrading to the Rogers 4.2.1.181 package and hope for the best. This sucks.
