I have a question about which running apps are important. Maybe some of the techno geeks here know this. Some running apps which I would like to stop/uninstall but don't know what they do are: PVWmdrmProxy, PVWmdrmService, com.smithmicro.dm, and HTC Sense. HTC Sense sounds important but I'm not sure. Maybe Yeahha or the guy with the midget mad scientist avatar could comment on them? Thanks.
