The latest and greatest in iPhone apps for those who love taking photographs is Instagram. And it's FREE.
It's as simple as: take a photograph, pick one of the great filters, share wherever you choose (see below). Check your feed to see what your friends have been taking photographs of.
Sharing: Connect your Twitter, Flickr, Tumblr, Posterous, Facebook and Foursquare accounts.
Now go and download it. And don't forget to follow me, I'm TonyaStaab.
