You could buy the Special Edition version of the Samsung Galaxy S III with those cute little Royal Guards that fit into the earphone jack, but that would require you to buy another phone, so that is out. Well, how about the Summer Olympics flip cover for the Samsung Galaxy S III? It is a battery cover for the unit that has a soft cover that flips over to protect the front of the phone. And the design consists of famous London benchmarks such as Big Ben.
The Olympics flip cover for the Samsung Galaxy S III can be purchased at the Samsung PIN pop-up stores that you will find around Olympic venues, shopping centers and around London. The regular flip cover can be purchased from Shop Android.com for less than $33.
