I imagine you didn't do a File->Compact Database in the process...and you might have a pair of clients for the iPhone in the database now, though it shouldn't be too hard to work out which one to unregister from the last sync dates in the Show Clients display in the preferences. Your database won't compact if you have an old client that isn't syncing, so you'll want to have a look at that (OF will remind you if you don't).

Note that it is possible to have many more zip files than actions if you do a bunch of editing. Each time you make a change to a date, or the rank (position) of an action, or the project, or the context, or edit the name and/or note (and close the edit), you'll get another zip file. It doesn't appear to do any coalescing of changes to a given action, either, if they were done separately. And, if you create an action, edit it a few times, and then decide you don't need it and delete it, all the zip files created in the process stay there in the chain until the database is compacted.
