Who needs a plastic keycard to let you into your hotel room when you can have a Samsung Galaxy S III (S3). As the primary sponsor of the 2012 Olympic Games in London, Samsung is getting involved in a big way. This latest collaboration sees them providing the official smartphone of the Games to 40 VIP rooms at the Holiday Inn London Stratford. 

The phones come with a custom application built in, and allow guests to express check in and out, change TV channels, activate the in-room air conditioning, order room service and even let themselves in to the hotel room in place of a keycard.  Oh, and since it is a phone, you'll be able to use it to actually call people too.
