"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.
