I am a Des Moines resident. Just thought I would mention that about three weeks ago (December of 2013), I was riding in the back seat of a car and noticed the 4G notice come up on my Sprint phone. I was located on south side I believe on Bell or Indianola Ave. Only lasted for a short while, but it made me think that maybe some work is going on to get Sprint 4G in Des Moines finally. Only been paying that extra $10 "data" fee for 4 or 5 years now!
