Shouldn't the live tile show missed calls? I don't get any notifications on the tile itself. The app is AMAZING, but if this feature isn't available, then it's a deal-breaker for me.
I have the original phone app pinnned right under...i think the special dialers don't have access to recent or missed calls.
RapDialer is just a dialer app, I doubt the developers have even thought of updating the tile for missed calls. RapDialer and the other dialer apps are not integrated into the phone system like that to be able to show things like missed calls, accept calls, or have a joint history. MS may not even allow apps to have access to those types of things. It's also not easy to have a tile which updates on demand like that, there are very few that do apart from the built in functions.
I guess the short of it is I wouldn't hold my breath.
NOTE:
Because of restrictions in WP7, many important features such as incoming calls and call history are unavailable in marketplace version. We will try to make them come true in other ways.
