I used WP7 Root Tools by Heathcliff74 and put a .wma file in My Documents/My Ringtones to use as a text messsage alert. The new sound plays for a day or so whenever I get text messages, but then all of the sudden I'll start getting NO alert at all. When I go to check things out, I see one of the standard alert sounds (like alert 10) will be selected, even though I get no alert sound at all! I either have to select another standard alert sound, or re-edit the value in the registry to get my custom alert sound working again, but the same thing happens all over again. Anybody run into this problem or know what's causing it?
Samsung Focus, by the way (NOT Focus S - I have both currently, because I haven't sent the original Focus back to AT&T yet for the replacement Focus S they sent me).
