Twitter - fixed the same problems at text messages but went public to put a different dynamic on it. Facebook - solved Photo Sharing, a constantly updated contacts book that is up to date with all of your info. Skype - Huge disruption, one of the biggest out of any startup. I stay connected with my Dad who travels a lot and with my family in Canada and America. Angry Birds/Tiny Wings - They're games, the same problems that people have been solving for thousands of years, Boredom. Pinterest - They made a huge distributed store and it'll become more like this over time, offers consumers millions of choices and lets friends curate those into boards making it easier to find cool things. Letting the small sellers rival amazon.
