U.S. Cellular might only be the 6th largest carrier in the United States, but it is steeping its device lineup with top-tier products. Only a day after the U.S. Cellular launch of the Samsung Mesmerize, they announced they will be offering Samsung's 7-inch Android tablet "in time for the holiday shopping season." They haven't yet offered pricing information.
While some might doubt a smaller network like U.S. Cellular, there is something to be said for their reputation as a company. The company's Belief Project attempts to improve the wireless customer/company interaction. Forbes has also rated them among the "Most Trustworthy Companies." In light of such scandal as Verizon's bill-inflation, we wouldn't necessarily mind switching to a smaller carrier.
