I have the Sprint Epic 4G and just recently upgraded from 2.2 to 2.3. Before the upgrade I copied my entire SD card to my computer. After the upgrade I noticed the memos from the stock memo app were missing. Would I be able to locate the save file from the stock memo app from all of the files I copied to my computer? Or are the memos lost for good? I didn't use any programs to back up my SD card. I just copied the contents to my computer. Not rooted.
