How do I download photos from LG VU (CU920) cell phone to my computer?

You can use the bluetooth feature if your computer also has bluetooth capability. if not, hopefully you're using a mini SD card. if your computer has a port for mini SD's, then just take the mini SD out of your phone and plug into your computer. if your computer has a regular SD port, then you need to get yourself a mini SD adapter. it looks just like an SD card, but it has a small opening to slide your mini into. if there are no SD ports on your computer, simply buy yourself a Flashdrive (thumbdrive) that has a port on it for mini SD cards. then, just plug that into your USB port.
if you're not using a mini SD card in your phone, then you need a data transfer cable, which you probably have to get from AT&T. i tried radio shack, but they didn't have them. In my experience, using a mini SD card provides the most compatibility. hope this helps.
