"Corrupt" ringtone and sounds.
I have a workaround for the following only:
Ringtones, Missed Calls, Voicemail, Reminders, Email, SMS and MMS
Note, it's a WORKAROUND only and with those events only, I've not seen any further issues of the corrupted notice, losing sound, etc.
I'd really like another person to test this out and confirm what I'm seeing before I pass it out to everyone. Just a 2nd set of eyes!
if you have MSN, ICQ, Yahoo or AOL messenger, PM me here and I'll walk you thru the workaround via IM.
