I bought my Captivate on 11/17/2010 and am confused with a couple of things. How do I make sure all of my apps, programs and things like that are turned off, and not draining my battery? How do I know if an app is using DATA or not? Is there a way I can tell. Also, What are some important apps that I can benefit from? And how do I upgrade my captivate to Froyo from Eclaire? P.S. I don't use any networking websites, so please, no apps to use those. Thanks so much for the help!
