I think the Eye-fi has a set up on their new cards to send images from camera to your phone over wi-fi, you could then upload to social media. And Eye-Fi cards work in all SD card taking cameras from my understanding.
A really neat couple of photos here that I thought you guys might enjoy. Seems like a fairly simple setup going on, but a real fantastic effect and mood set with the lighting. Makes me think of old neon lights from old highways. Hope you guys enjoy.
OK, so I configured it to shoot raw to the CF card and JPG to the Eye-fi card. When I review my pics it looks at the wi-fi card and then when I "protect" one it sends it to my iPhone where I can mess with it or send it further!
Meanwhile Canon announced the Elph 320 point-and-shoot that has built in wifi.
