Regarding "3. Privacy", it's not just the network you're on, you're protecting your privacy from, it's every single service your device regularly polls or connects to. If you find yourself hopping on and off wifi at home and work and else where, every service your device polls is building up a log of your movements. This is mainly why I have a VPN on my phone. Apps that make internet connections from my phone always appear to be coming from the same IP address as far as the end service is concerned. It doesn't matter if I'm on wifi at home, on wifi at work, or on 3G. All of the connections are routed over an encrypted channel to a box I control before hitting the Internet.
