It is the international version that is going to be available unlocked in black starting on Wednesday. The phone originally launched in Marble White or Pebble Blue and some new colors have been added over time. Expansys will have the unlocked, black Samsung Galaxy S III priced at 409.99 GBP ($657 USD). We're not sure if this price includes VAT, but what's the difference? You're getting a black Samsung Galaxy S III! AT&T or T-Mobile customers will be able to use the device in the states. The question is, are you so much better off having a black model of the phone with a quad-core processor that you are willing to skip on LTE connectivity and 2GB of RAM?
