I've had sprint for prob 10 yrs, but sprint 3G only since the 4S. The data has been atrocious(.12mb avg) since day one. They always say it's getting worked on. I decided to try the 5s to see how the LTE was. It's good but I don't get it unless I drive to a town 10 mins away. I returned the 5s w/in the 14 day window and the bozos at the sprint store were incredulous. Needless to say, I miss the touch ID and slightly faster loading on certain apps, but other than that my 4S still works like a champ. Guess I'll wait for that 6.
