It might be a noob-question, but here goes: In my area there are a lot (a LOT) open wifi networks. My HTC Desire has the capability to auto-connect to these networks, but I am hesitant to enable this option. While a laptop working on an open Wifi is a risk, I am unsure on what the risk is with an Android phone. So my question boils down to this: is the auto-sync connection safe for use on open wifi networks? If yes, which connections are NOT safe on open wifi (like latitude, maps, the browser, etc)? And if no: is there any way to make it safe? Like using a vpn on a laptop or something similar.
