you should try Dropico then,
it let you Simultaneously share to:Facebook, Twitter, Tumblr, DailyBooth, Posterous, Foursquare, Flickr, Picasa, PhotoBucket, ImageShack and Dropbox.
(saves the photo to a real album on facebook)
& 25 amazing filters.
You can also set up a private, cross-service list of “close friends” – from Facebook, Twitter, e-mail.
Then simply shoot photos on your iPhone, and simultaneously share them with any friends you choose on your private list.
There’s no need for Dropico on their end – photos will seamlessly appear on their
network or service of choice – as private Facebook posts, Twitter DMs or e-mail messages.
