Instagram update blocks Instance and other apps that offer third party uploads

"We recently made an update to the systems that we use to fight spam to help prevent future attacks and increase security. As part of this, applications accessing Instagram against the terms of our API may also be affected. This update does not specifically target any particular app or platform."-Instagram
"There's no need in being mad at Instagram. It's their service and they have very right to hold the keys. I'm just trying to pick the lock. I'm very sorry to everyone that bought the app and can't upload. I'm doing my best to fix the problem."-Daniel Gray

While Gray is obviously disappointed, he says that he holds no grudges against Instagram and his main concern is for those who bought his Instance app from the Windows Phone Store for $1.49. He also has a Pinterest client for the platform called Pinsation. While Windows Phone users might end up having to wait for an official Instagram client, the Nokia Lumia 1020 comes with Instagram rival Oggl on board.
