I have the 64GB wifi only version of the iPad 2. I'm currently looking for places to go that have free SECURE wifi. Every place that I've gone to (McDonalds, Borders, Barnes & Noble) the people that work there can't tell me what kind of security they have. And that INCLUDES the managers. I want to start using my iPad at bookstores, coffee shops, etc. But obviously I don't want to use unsecured lines. Any suggestions?
