I'm trying to sync my contacts to the SD card as a nother back up in case my phone breaks or something (I've had 3 iPhone 4s break in the last month). I go to people, settings, import/export and choose export to SD card. I then choose phone and it asks me to confirm. I confirm then a box pops up for a half second and all I can read in is "failed to initialize." Am I doign something wrong? Or is there a reason or something wrong with the phone and/or SD card?
