Maybe the device switch option will work, IDK. I have a Curve 8310 I don't use much anymore, but when I tried restoring my Bold backups to the Curve to keep the calender/contacts/etc the same on both (in case I take the Curve out) the calender and address book won't come out of the IPD files. They're greyed out. I used the Restore Backup otion to transfer them to the Bold, but I guess that's a one way street. I'll try Device Switch when I get my Curve back (it's currently touring Europe with my friend. I unlocked it so he can use it, and try a BB out)
