How to change the ringback tones
 

There is something I have always been meaning to ask.

When my N900 establishes a VoIP connection, I always get a continental European ringback tone (425 Hz I think). However, I would prefer to hear an Irish or American ringback tone which sounds more like a buzz (350Hz/440Hz ). Is there any way to switch this?

And, yes, I do realize there are more pressing issues to deal with on this planet. ;)

Seriously, nobody knows of a way to tweak this? I can't believe that... :-)
