LG CU500

Does anyone know how to get the text messages off this phone? I have some info in some message that I need to save, so I wanted to make a backup of the whole message list to my computer before my phone dies and I loose everything (it went through the clothes washer, but I was lucky this time and it sort of still works). I can't find out how to transfer them via bluetooth. I don't have a data plan, so no internet access and I don't have a USB cable and they aren't stored on the SIM card.
