I'm relatively new at this. I've never actually used Wi-Fi on a Blackberry before (since I used to use the Blackberry Social add-on on my previous BB, so I never had to worry about data since it was unlimited.) So I'm not sure what I'm to do. I have gotten onto my home's Wi-Fi network, however, I don't want to be charged for data while I'm on Wi-Fi. Is there something that I need to do in order to not be charged? Also, on my old Blackberry, there was an option where I could have Facebook refreshing every hour as opposed to every 5 minutes or whatever it is. I want to be able to save my battery's power. Is this option also on the Z-10? I can't seem to find it. Any answers or tips would be great.
