I had a lot of problems migrating from my 7100 to 8700. A selective migration always gave me a problem, but I ended up getting a full backup of my 7100 and then full restore to my 8700 to work.

Only problem left is I have all my old .adp ringtones still on my phone. How can I delete them from my phone? What do I have to "Clear" in the Advanced backup/restore area to remove them?
