After a week of trial and error I have finally found drivers for my USB cable. I am using BITPIM and am trying to install some new ringers. I chopped some mp3's down to 30 seconds and am trying to load them on my phone (they are about 500k in size each). Every time I go to Settings/Sounds and try to go to the download tab my phone automatically turns off. For a split second I can see my ringers on the screen then the phone shuts down every time.
