The official phone of the London 2012 Olympics known as the Samsung Galaxy S III is now up for pre-order at Amazon.com. The Galaxy S III is selling an international version of the phone for $799.99 in either blue or white. The blue version starts shipping on May 29th and the white one is expected to start shipping on June 1st. The S III will be compatible with AT&T’s HSPA network, but it won’t work on LTE. If you use T-Mobile, you likely won’t get HSPA because the S III lacks support for the 1700 band. The device also will not work on Sprint or Verizon since it is not a CDMA phone. Your best bet here is using AT&T without LTE data speeds.
