This is a stupid question I know, but I have googled with no luck. Is it safe to use apps like facebook, tweetie, or sites like gmail from my ipod touch at public wifi hotspots? We are staying at a place with free wifi, you just have to go into safari and accept their terms and conditions to access the web. I’ve been scared to go to any sites where I have to put in passwords or personal information. Is it safe? Does the VPN feature provide any protection or is that for something else? Thanks.
