I have V400. Its MP3 ringers (Okay, I assume the default ringer
and other tones are in MP3 format) don't sound loud enough in a
noisy environment when the volume setting is at Loud. I work on
NYC streets so it's quite noisy around me. I have missed calls
almost daily. In comparison, V60's beep tone seems to have a
better chance to penetrate the noisy place and reach my ears. So
is it possible to use V60's beep tone or similar tones in V400?
