Hi, I'm having trouble uploading a ringtone to my LG TU915 cellphone. I already have the .mp3 file on my computer, I downloaded it to my phone using the phone agent, and I can see and play the song under the Ringtone menu. However, there isn't an option to set it as my ringtone, unlike the other ringtones that already came with the cell. I was just wondering if i'm doing something wrong, or is it just not possible. Thanks.
