Anyone notice the battery has an integrated water damage detector? I know some of the folks here are covering the detector on the side of the phone. I think HTC is trying to be a little tricky!
I would suggest you cover this one as well, especially with the lanyard hole so close to the battery. I can see it getting damp with little effort.
Here are the damage indicators located inside the unit (3) which makes for a total of 5 on the entire phone (1 on battery, 1 on side under battery cover) ...Talk about paranoia!
