Just a general use question for iOS 4.1: Do you use your apps and just hit the button to close them and think nothing of them anymore? Or do you double tap the button, hold down on the icon of the running app and then kill the app that way? The reason I'm asking, I'm doing it the latter way most of the time and it seems to be quite cumbersome. Should I just not worry about it and just have faith in the iPhone to manage the apps that are open? The only thing that I would worry about is an app like Motion GPS that will reach out on the cell network even in the background...using up data bits from my plan. Anything else that may do that? Just curious.
