I upgraded to a 8GB microSD recently, and formatted it on my device, then transferred over my files from my smaller 2GB microSD. Now movies, music, photos all are viewable and work fine, but the phone isn't reading my ringtones t hat areon the MicroSD, it reads only the ringtones stored on the actual device. Any suggestions folks?

i upgraded to a new 8gb card a week ago without any problems.
is it possible that you copied over the old bbthumbs.dat file when you copied over.
i dont know if that would affect anything though.
but i have trouble sometimes with my media card not showing files sometimes. i would do a battery pull and see if that helps

I have an issue when I first got my 8900 is wouldn't read my 8GB card at all, in the end it I needed a new handset

Did you have the same folder layout on yout 2GB card as you have on the 8GB card
