It has been 30 hours and no issues.
The more I think about it.. (and I find this very odd). My BB died on tuesday night just hours after adding some MP3s (Joe Pass in case you care). My third (and current) 8110 that was dying had the same mp3s on it.
I am going to format the microsd card (using an 8100) and pop it in. If everything is ok I am SURE it is those mp3s (DAMN YOU JOE PASS ;).
WIll let you know tomorrow evening.
