Long time lurker, first time poster.

I just got my Centro a few months ago and with unlimited data, I'm customizing the Internet apps. I've been using MiniTones since Day 1 when I had my Trēo 680 (R.I.P.). I have a "You've got Mail" (.midi I think it's MiniTones output?) that shows up in every other app that uses the preloaded sounds (prefs, sounds, calendar) but when I go to change my alert sound in XpressMail, it's not listed. Any ideas on getting that cool tone to work?
