LG UX 355 and mp3 ringtones

I have a LG UX 355 and I uploaded an mp3 ringtone to my phone via USB cable, I can see it listed but I just can't set it as default. How do I get it to work? Thanks for any help!

How did you get the song onto your phone? I have the cable. What program did you use?

I bought Datapilot and downloaded it to my computer, transfered the mp3 ringtones but I just can't set them as ringtones. Does anyone know if USC disabled that feature so we have to buy the ringtones from them instead???

I'm trying to help you figure this out as I try to figure it out too. What was your phone settings set at when you transferred from datapilot? USB or RS-232C. Either number 1 or 2 under data settings.

It was and is set at USB under data settings.
