I just got a Motorola RAZR V3 when I changed my cellphone plan. It is a really nice phone that I can connect to my computer using a USB cable. I decided that I wanted a custom ringtone instead of the default. It's not a difficult process at all but there is a lot of information scattered around the Intarweb that makes it difficult. Here is my summary process: # Find something you want to use as your ringtone. It can be an mp3 or wav file or whatever. # Convert to wav file if its not already there, minimal survival command: mplayer -ao pcm filename.mp3. You should now have a *audiodump.wav* file. # Download and use Audacity to cut the audiodump.wav to about 20 seconds (mine is 18) # Save the clipped wav file and then encode it to mp3, minimal survival command: lame -b 64 -s 44.1 -mm --tt "Title" cutsound.wav output.mp3 Basically, the RAZR V3 needs to have mp3s at 44.1kHz, 64kbps and under 200kb for it to be used as a ringtone. Once you have the file, you need to upload it to the phone using moto4lin. Connect to the phone and place the file in /a/mobile/audio/. Change your phone to *Silent* and then delete MyToneDB.db and TempToneDB.db. Power cycle your phone. Once your phone is back on, change your phone to something other than *Silent* and then browse for a new ringtone. You should see the name of the uploaded file.
