Would be nice. I've been eying Cricket for a while because of those cheap unlimited plans. I'm still going to wait and see if they do, but I think Sprint or U.S. Cellular will be more likely to purchase said divested markets.
USCC has intentions of acquiring certain divested markets (regardless of 850 or 1900 network), while Sprint will only go after PCS networks. Sprint has always stayed away from lower band frequencies, which is why they never participated in the 700 band auction. So any Alltel markets they acquire would have to be for the PCS network only.
