U.S. Cellular isn’t one of the major carriers you’re used to hearing about, but they do serve about 6.1 million customers in 26 U.S. states. That’s why, whenever they have the opportunity to add some top-notch Android devices to their lineup, it gets everyone excited. While there hasn’t been any official announcement, a screenshot of their ESN system shows both the Samsung Galaxy Tab 10.1 and the Samsung Galaxy S II, which is usually a good indication that these devices will be available soon.
