usb bluetooth or data cable?

which will give u a faster transfer rate the usb bluetooth device or a datacable, i'm thinking in regards to tranfering mp3 files

What phone are you using?

nokia 6600

if its transfering big files, mmc card reader is the fastest. but u cant install apps/games wif the mmc card reader.

bluetooth is slower, but u can install apps/games (they are sent to inbox, install from there).
