G-profile: Has anyone use it?

Has anyone used G-profile from http://www.ageye.de/index.php?s=gprofile/about

I'm looking for a good program to switch between sound profiles like the one in the HTC Touch.

I sleep during the day and I have to silent my phone while I'm sleeping but I have to allow a couple of people to wake me up if they need to reach me. So I have to assign a ringtone for each those people, then I have to go to sounds and notifications and change the ringer for the incoming calls for known callers, unknown callers, etc one by one. I select the "No Sound" ringtone and is a pain having to this everyday when I go to sleep.

I was wondering if G-proile is any good but I'm afraid of installing and having to hard reset b/c it didn't worked.
