any suggestions for programs to d/l to convert mp3 format to aac or wav?
where do i save the songs in order to set as ringtones? how come i cant bluetooth songs from 6230 to 7610?

You can use a program called DB Power Amp Convertor. You'll need to download the AAC/MP4 Codec as well. I presume you can't Bluetooth songs because they are copyrighted information.
Save the MP3s to E:/sounds/digital to use as ringtones

Where can that program be found? Is there a nice page with freeware programs anywhere?
