So I've run into an issue where I can't access any files on the SD card while the phone is charging. I've got the USB connection type set to Charge Only but I still get the message that the SD card is unavailable because it's being used as USB storage. Any way to get around this? Not to beat a dead horse but I can't NOT charge the phone at some point during the day as I play and stream music all day at my desk. I would really like to leave my iPod touch at home and just use my phone to listen to my music.
