If you open your battery door there is a little circle to the left of your SD card. There are a couple red X's on white paper. this is how verizon tells if you dropped your cell in water. the X's change from red to a different color. i wanted to know id anyone thoguth it would be a good idea to cover the hole with tape. the tape would block water from toughing the paper with X's. what do you guys think?
