Samsung just unveiled the Galaxy S III during a press event in London. We’re there reporting live, but we also just caught wind that Samsung is planning to launch a 4G LTE-equipped version of the Galaxy S III in the United States this summer. Europeans, however, will be able to get their hands on the HSPA model as early as this month. Samsung didn’t specifically say which carriers will offer the Galaxy S III this summer, but we’re guessing both AT&T and Verizon Wireless are going to get on board this ship. Pricing, retail availability and exact timing were not disclosed by Samsung.
