It's the easiest thing to trim a piece of music and upload it as a ringer on most sanyo phones but when it comes to the 3100 - I'm buggered if I know how to do it. I thought I had it but the phone continually comes up with error message 901 'Insufficient Memory' even though there's 600kb available. Does anyone know an easy way to get a trutone piece of Led Zep - 'Stairway' or Dylan - 'Knocking' loaded on?
