If you check your palm install directory, there's a subdir with your lastname + first initial. under that, there's a backup folder. If you move all the files in the backup folder somewhere else, then sync with your new 7135, only the data for the 4 built-in palm apps (addr, datebook, memo, todo) will be transferred. I suggest backing up the directories for the 4 palm apps, in case something goes wrong.

Minor setback for me:
I lost some addr categories when I first sync'ed because I had deleted some of the default Palm categories and created 15 of my own. The sync process is too dumb to see that I wanted those default ones deleted... since 15 custom categories is the max, it deleted my own categories that went over the 15.

So I just restored the addrbk folder from backup, deleted the defaults from the 7135, then sync'ed again, using "desktop overwrites handheld."
