Instagram gets sharing capabilities with Tumblr and Posterous

Instagram has just released an update for their mobile app that improves upon the sharing capabilities of the service.

Instagram already supported Twitter, Facebook and Foursquare. They have added support for Tumblr and Posterous blogs.

It is now pretty much at par with PicPlz in terms of third party support. Dropbox is one important service missing. Though Instagram does offer the email option.
