I'm having the same problem. I downloaded a program called WebJAL, it seems to be good...but I'm trying to do the opposite...transfer ring tones from one phone to another...and can't seem to figure that out... I'm pulling my hair out over here...!
I have a v180 also and i could not get the cable to work at all(probably just my lack of computer savy) I ended up getting a program called ringfactory. it works fairly well, it sends a text message to your phone and you follow the link to download ringtones or backgrounds. not sure how it works for multiple phones tho.
