Kudos to the CodeBook team for this enhancement. I always thought it was inefficient to toss the whole database over the wall. With the new system even in places were I have bad cell coverage on my iPhone I can sync quickly, since typically only a few entries change between sync events. And the old database is still with us locally, so full query functionality remains.
Thanks very much for your support of Codebook and for the kind words. It means a lot to us!
Have a happy holiday!
