I have an Iphone 4. What is VPN and should I turn it on?
I dont think you'll actually need VPN ever. VPN stands for virtual private network and that just means your phone will be on a network that no one can trace (connecting to school wifi and you can access sites your school has blocked, but they caught that now). You really dont need vpn.
Unless you have a specific reason to use VPN, don't bother with it. VPN is a networking protocol designed to create private connections to s specific site or server. You have to have it working on both ends, so unless you have such a connection, you have no use for it.
