SD card method doesn't seem to work for 13xx. See my answer [Only registered and activated users can see links.

Try lolypop000's method from [Only registered and activated users can see links. Click Here To Register...], it worked in my US1300. If not, try all the others and report ;)
Edit: The link in lolypop000's post seems to have died. Here's a mirror: [Only registered and activated users can see links. Click Here To Register...].
