even though it doesn't show it on the clear.com/coverage website there are actually 2 towers turned on in des moines. there is also a tower that just came online in marshalltown, another in olwein, and one in davenport. so they are there, just not the best coverage :/ a coworker of mine as an evo shift and we found one of the towers in des moines, was sitting across the street from it and only had 2 bars, got 5meg down and 1meg up for speed test.
