I just got my phone last night. I was playing around with and when I go to Settings>Applications there is something that says "Running Services." When I select that there are apps or something "running." What are these and why are they "running?" I'm on wifi at home but when I'm out and about and not on wifi are these things using data from my data plan? Do they need to be running all the time? I'm obviously new to this kind of phone so any help will be greatly appreciated!!! Thanks!
