Sure you are on a 3G connection? For example I have sprint and when I lived in Ohio a while back my 4s would fully utilize both 3g connections and speed was never an issue, but I've moved to Washington and the speed here is pathetic and I'm fairly sure the cause is a limited 3g, but primarily 2g connection in the area. Anywgo download the speed test.net app Nd see what your network is producing.
