Samsung Galaxy S III replaces check-in, keycard, TV remote and AC control
 

Samsung has turned the Galaxy S III into the ultimate hotel accessory in preparation for the Olympics. It's equipped 40 rooms in London's Stratford Holiday Inn to use the official smartphone of 2012 to check in and out, order room service, unlock doors and control the TV without moving. VIPs staying at the hotel for the games season will get first dibs on the technology that'll let them call up a snack whilst tweeting -- just as long as Cody Brocious doesn't work out how to intercept it.
