Found them on the apple discussion boards a while back, they fix apple products as well as buy your old apple crap and give you cash I have sent in a few IPods and gotten some good money for them. I believe they can fix your IPhone screen. Looks to be pretty pricey though at a cool price of 209.
My coworker also broke his glass but he was able to return it to apple and get a brand new iphone. You should try making a appointment with the genius bar and see what they can do.
