Sprint was clearly hungry for capacity when it bought spectrum from US Cellular last fall, and it's at last getting its fill -- some of it, at least -- by closing the deal today. The carrier has officially taken possession of 20MHz in airwaves across Midwestern cities like Champaign, Chicago and South Bend, as well as 10MHz in St. Louis. The customer handover isn't quite as grandiose as was mentioned in November, however: Sprint is ultimately adopting 420,000 US Cellular customers, rather than the originally claimed 585,000. It should be a relatively bump-free transition, no matter who's included in the group. Sprint expects the switch to take several months, and it's keeping the US Cellular network active while customers go hunting for discounted phones.
