Yeah, I only lasted a few weeks before I got another 4s.

The Lumia I had could not even make reliable calls in my house, same network.
Once a year I get stupid with phones. This year I was trying to upgrade my wife to a better plan/phone. Strange circumstances and all of a sudden she is using my iPhone 4S.
The iPhone 5 is better in terms of specs, but I have tons of accessories for the old connector and prefer the iPhone 4s heavier feel.
