As for the condensation problem. You can get silica gel packs. you know, the little white bags that read "do not eat" you find in shoe boxes and electronics. You can buy a box of 100 for really cheap on e-bay and other websites. I have one taped to the inside of every book behind the rings, in every card box, and a few just laying on the back of every shelf. I have one in every desk drawer in closets. in the back of my amps, in guitar cases. Photo albums, inside my computers, they are great. If you live where the humidity is high they are a Must.
They are so good that if you drop your phone in water. put a hand full of the packs in a ziplock with your phone and in a day or two, depending on how wet it got, it will work again.
you can find videos about them on U-tube.
What is that behind you!?! Oh, It's me! Looking at the cards you have, That I want. :)
