No. The spectrum situation in Cedar Rapids is different. In Des Moines and the Quad Cities AT&T has either PCS Block D (Quad Cities) or E (Des Moines). Sprint's PCS B block spectrum sits in the middle of D and E. So a B/C swap gives Sprint 40 MHz of contiguous spectrum in C+G and AT&T the same in B+D/E.
In Cedar Rapids, for starters Sprint doesn't have the entire PCS B block to trade, they split it with AT&T. Furthermore, US Cellular holds the PCS C block and no additional PCS spectrum. There isn't a trade to be made there. The trades involved in this AT&T/Sprint transaction were rather obvious.
