Samsung Zeal / Alias 2 SCH-U750

I'm one of those audacity guys... We've gotta figure out how to put our homemade's in the My Ringtones folder on the SD card! I've noticed that we can still email them to our phones and save them to the phone, but it seems that with the newer tech in these phones, higher bitrates sound better... As we all know, higher bitrates = more memory...

I'll be workin' hard on this, but any help would be much appreciated...
