Swung by verizon today. The button you push down to be able to slid off the back cover broke. A little tab broke, and then the button and spring came out. A rep messed with it for a couple minutes, and then started making calls. I'll have a new curve at my door Wednesday at the latest.
Major thumbs up to Verizon. I take very good care of my phone. This was the first problem I've had, and they seem to have handled it very well.
