And that makes four: Verizon, AT&T, T-Mobile, and Sprint have now come out with more details on their versions of Samsung's Galaxy S III. Like T-Mobile, Sprint has committed to launching the phone on Thursday, June 21st, but Sprint's adding some details on SKUs and pricing as well: there'll be a 16GB model for $199.99 and a 32GB for $249.99, though the latter will only be available online (meaning you won't be able to walk into a store and pick one up). As is the case around the world, "Pebble Blue" and "Marble White" are your color choices.
