I bought a 32gig Micro SD card to replace the 2gig it came with. I put the card in and it set it up as per normal. That was nice. I then copied all of the folders and files on the original, put on my computer, then pasted to the new card. I had it merge the duplicate folders and rename the duplicate files. One thing I noticed is the ringtone assignments I had made under my contacts were totally messed up. Mostly I am curious for why that is (did the paths change somehow?) I don't see how it would have replaced with other ones though instead of just going to default. I guess it would also be nice to know so if I do this again. I already manually fixed all of them, but am still curious.
