I gather .ogg is a sound file type that the DX (and prob others) for ringtones and such. I see where it keeps them in the system/media/audio/notification or ringtones. Seeing that the DX can use even mp3 format for ringtones, can I put in any format file to the notifications folder and subsequently use that as a notification tone instead of the factory notification sounds? I have quite a few downloaded clip files that are just quick mp3's that I used to have on my BB, which could assign any sound for any thing, email text, call, calendar, alarm. The DX can't assign custom sounds except for ringtone. email text and such, is sol (that is unless I'm missing something). Yes, I know I could run another app to get around it, but I'm not interested in using another app for just ringtones and sounds. I would like to just place files in there and have it work that way if possible.
