I am far from an expert although this is what I have found since my .148 upgrade; on my home screen, I have an icon for messages (not email or SMS, it just says messages).  This icon recorded my missed calls and I would go to that icon and be able to view my missed calls.  I found that going to the new phone icon I have; I can go to options, go to call logging and then check all calls.  Now this message icon acts as my call log recording inbound/outbound and missed calls.  I push the message icon and have access to all calls.  Hope this helps out.
