I upgraded OS from V188.8.131.52 to V184.108.40.206 yesterday. It went pretty smothly, with only a few retrys. The main BB use for me is to sync Outlook and the BB, for Addresses, Calendar and Notes. After restoring data from LoaderBackup, I find no Outlook Notes on the BB. I can still see Notes on the PC, but don't know how to restore them to the BB. I'm afraid a Sync will wipe the PC Notes data. And Desktop Manager Restore doesn't show that level of detail.
