Had a frozen water in my cup holder that sweat all day, didn't even drink it, well that evening I brought the water in before heading out. Well I have a habit of putting my BB 7100t in the cup holder so if it rings I can just glance down and see who it is. Well when I got to my destination and picked up my BB the screen didn't come on and it felt wet! Come to find out I had a 1/2 inch of water in my cup holder well that night I took out the battery and laid it out to dry overnight. Said a prayer before going to bed, well that morning the Good Lord answered because I put the battery back in and it turned on and has worked great since.
