Samsung’s new flagship smartphone may launch on all four major U.S. carriers as well as a number of regional carriers beginning this summer. Samsung on Thursday unveiled the Galaxy S III during a press conference in London, and the vendor said its sleek new smartphone will launch on nearly 300 different wireless service providers around the world in the coming months. At the same time, Samsung added a page on its U.S. website that allows users to sign up to receive more information about the Galaxy S III when it becomes available. On the page, a drop-down menu asks users to select their carrier preference, and found within that list are AT&T, C Spire Wireless, MetroPCS, Sprint, T-Mobile, U.S. Cellular and Verizon Wireless. While this is by no means confirmation that the handset will launch on each of the seven carriers listed, it seems unlikely that Samsung would simply list random carriers and omit popular options such as Cricket, which currently offers a Samsung smartphone, and other sizable regional carriers. Samsung’s current flagship phone, the Galaxy S II, is available from all major U.S. carriers with the exception of Verizon Wireless.
