Task Killer shows Sprint Nav even after force close!

Won't matter. It'll keep rebooting even if you keep killing. IT WASTES BATTERY to keep killing it because it sucks battery to reboot it everytime. Conversely (and not as intuitive), it SAVES BATTERY to just let it do its thing and sit idle. It doesn't eat much battery at all in comparison.

Check HERE for my results using a task killer vs. going 100% stock. Android is smarter than you are....and if you shut off the sync features of the major battery killers, the other apps running do not cause major drain. Task killers are deceptive.
