Yesterday I installed Advanced Task Killer (Free version) of the market to give it a try to see if it would help me save some battery, it has so far from what i've seen. I close out apps like Sprint Navigation, Fring, Voicemail, Amazon MP3 Store and 1 or 2 more apps but then about an hour or two later those apps are back on and running. Does anyone know why and how to shut them down completely?
