I was traveling around today and had various unlocked wifi's come up on the phone. I had 3 full bars but when I went to check safari or send an email... it said "cannot connect to server". I thought I would only get this message if I was trying to get on a locked wifi. Why wouldn't I be able to use any of these Wifi spots? I'm now questioning the value of wifi in the phone except for home use. Am I doing something wrong, or have bad settings to where my phone will only talk to MY network? It's puzzling me why I see the 3 bars but it doesn't work. Thanks.
