I got my iPhone 5 last week. It was connecting to the internet just fine, until today. Well I stay home most of the time and use wifi, but when I went out to have dinner with friends and tried to go online, it won't connect. I had full bars, and it does say that there is LTE. But then I get a "no connectivity" message. I tried my friend's ip4, and his ip4 was able to connect to the internet just fine. It was embarrassing that my supposedly better iPhone5 could not connect to the internet. I tried everything from turning my iPhone off and then on, resetting network settings, resetting all settings, but there's still no connectivity. This is starting to annoy me. The reason why I love my iphones is that they're consistently dependable. This is the first this has happened, and I hope they fix whatever the issue is. Will be calling AT & T tomorrow.
