Thanks GoDJ for the post! Here's my take:
1) Make sure to do a backup before beginning any of this
2) My Pearl 8100 doesn't have Desktop [SYNC] and I'm not a BES user
3) I tried adding the YM service book, but it replaces my existing books (no more email). Restore, email and other books back, whew.
4) I don't see a way to combine or insert the book as one user suggested (unless that user doesn't use email and didn't notice it overwrote it?)
5) Shame on AT&T for being so greedy and forcing all of us to waste time with work-arounds.
So, anyone know what I may be doing wrong, or is there a way to "merge" YM's service book into my Bberry?
Thanks!

Bottom line: Inserting YM service book does wipe out your existing books, but going to BIS site you can have them resend your books which doesn't wipe out the YM book you just added. Make any sense? Hope so.
