Dropped my N1 yesterday (about the 3rd time it's hit the ground) and spiderwebbed the glass(phone still works fine, it's just the glass front). Called HTC support and was quoted $55 for the repair(Free overnight shipping is included, both ways). The support call was one of the best I've encountered, guy was thorough and friendly. Turn-around time was quoted at 5 days (then upon finding out I was in Canada, 2 days was added to the estimate due to Customs).
Will keep posting updates.
