Instagraph (Version 1.0)
Venetasoft

After a long wait, there's finally a Windows Phone app which lets you upload photos to Instagram. The initial release was plagued by two main problems. First, uploading a photo would send it into a queue, causing it not to be so "insta" in terms of sharing your photo. It would take anywhere from 5 minutes to up to 30 minutes for the photo to show up on your photostream. Second, the photo that actually appears on your photostream would sometimes not be yours. Venetasoft quickly pulled the app and shut down the servers to work on a fix and have recently updated it.
