Best Way to add ring tones

This has lots of useful information on the subject.
There are also 2 utilities for making your own sound files louder - but I haven't used those.
Once you download the Zip files, you have to unzip them and then copy them to your device. You can "explore" your device through ActiveSync and just copy and paste from your desktop to the 6600.
Next, go into Phone->Tools->Options->Phone. Choose the ring tone yu want to experiment with.
I found the Classic tone (already on the device) with ring type "Increasing" to be somewhat OK.
