Is there any way to set up the S5570 as a mass storage device on my PC. The reason for wanting this is to provide a simple method of transferring mp3 music files from my PC to the phone via the USB cable. I have the Galaxy USB driver installed. With previous mobiles it was simply a case of connecting the phone to the PC and the phone would then be automatically recognised and displayed in Windows Explorer as a new drive. I can't see any way of doing this with the S5570. I've found the Tethering sub menu which says that it is for USB use, but it doesn't seem to do anything in particular.
