DIR=$1

mkdir -p $DIR/iPhone

cd $DIR
for f in *.mp3
do
  filename="$(basename -- "$f")"
  extension="${filename##*.}"
  filename="${filename%.*}"
  afconvert "$f" -o "iPhone/$filename.m4r" -f m4af -d aac
done

sh ConvertMP3_To_iPhone.sh /Users/MyUser/Desktop/sounds

Then you can copy the .m4r files into iTunes Tones directory/screen and sync with your phone.
