Regional carrier US Cellular is releasing its Samsung Galaxy S III only a few days after AT&T. The company has confirmed that the 16GB version of its Galaxy S III will be available to buy online by Wednesday, July 11th; it will be available in stores by the end of the week. As we reported previously, the 16GB version will sell for $199.99 on contract, but only after a $100 mail-in rebate. The 32GB version, which will be only available in white, isn't coming at the same time, though: it will be available "shortly" after the initial launch. We haven't heard when pre-ordered phones are arriving, but we wouldn't be surprised if they started showing up soon. Meanwhile, Verizon's version has been pushed back until July 12th.
