I've only had that happen a couple times. What does happen about once a day though for me is the screen gets all jumbled and freezes. Then I have to do a freakin battery pull!
I just downloading 230 last night. So far I really like it as for the white screen on the main screen. I changed the home screen layout to be today current, and that seemed to fix that. there still seems to be some over lay issues in the tool bar but I can completely deal with those now that it seems so much faster and responsive
