How can I find the latest added contacts?

Question

Hi,
I'm syncing my Address Book with my Nokia 6233, and it works fine. However, the 6233 has limited contacts memory (500 entries), so I had to create a special group within Address Book which is the one synced to the phone.
Problem is, whenever I add a new entry IN the phone, and later sync, the entry in question is put in the "All" group, not in the "6233" that I created. If I don't pay attention and remember which entries I put in the phone, and move them to the "6233" group, they are deleted from the phone during the next sync (because they don't belong to the "6233" group, of course).
My question is: how can I get the list of the latest added entries after a sync? I tried to do a smart group based on the modification/update date (which every entry has), but I can't: Smart Group don't offer a "last modified on" criteria, as iTunes does, for instance.
Using Spotlight to look for the string "Updated: [date]" (which shows at the bottom right of each entry) did not work either, probably because the data is wrapped by XML code that makes it understable only for Address Book.
Thanks for any suggestion,
bat

Besides getting a phone with more memory, and besides sending thank you notes ("It's been nice knowing you, goodbye forever!"), I can only think of specifying a field to mark the entry on your phone.
For example, perhaps putting 6223 in the notes. If your phone has a notes field, then that should work. Then the Smart Group in Address Book could search for 6223 in the Notes field.
As for your Spotlight search of "Update: [date]", I believe that didn't work because what you see in Address Book is just the interface, just some text for your convenience that isn't necessarily stored. In other words, the "Update: " part is just decoration. Nice try, though.
What I found works when searching for contacts based on modification date outside of Address Book is to use Finder's Find (in the File menu), or Command-F. For the first criteria, you can choose "Kind" and then "Other…" and then "Address Book Person Data". The next criteria can be "Last Modified" to narrow the results down to those which have been modified since a certain date, such as by syncing. I'm not sure how useful that will be for this scenario, though. The contacts will be listed by people's names, at first. Unfortunately, the names will end up becoming the undistinguishable file names being referenced for the search as as you scroll.
