I ordered a case online that has a slight magnetic closure (it snaps closed when the 2 sides get close). I always thought you should keep magnets far away from any kind of data storage device. After I started using it I had some problems finding files on my SD card. I took it out, and everything was there, put it back in and it was okay. Does anyone know if it's okay to use this kind of case? I'd hate to wreck my phone for a cute case!!!
