bluetooth? I need to sync my contacts and my data with the computer for backup purposes. I believe the data backup service with sprint is a monthly service fee. I really only need it on my computer. Any ideas? I have tried the usb cable, but when I plug it in, it says I need the software for the lg usb device and does not even show it on the computer. As far as I know there is no software for the phone to hook to the computer? Please help.
