Hi, I just registered because I needed to see if others are having the same problem I was.......no internet connection with my iPhone 5. I've been at it for close to 3 weeks and even bought a new router. Just as I lost all hope and followed everyone's suggestions, I found the culprit ...an app by the name of onavo. Once I deleted it, my web connection came back! I know this won't help most, but it may help someone, so I'm posting it.
