I have broken the screen twice (never happened with any other phone). The first time, I sent it into Motorola, and 2 weeks later I received my new phone. This time I bought a cover, and dropped it from sitting height. The screen shattered... I am not replacing this one. I am VERY disappointed in the quality of glass, and I am sure it will break again if I have it fixed.
Sorry, I know this does not help, I just had to vent.
