I've just acquired an iPod touch and I'm in love.

One small issue, though. I've added a bundle of addresses in the past few weeks using the touch, but only yesterday did I realise that they could be placed in groups if you were IN the group already when you started adding the new entry. So there's a whole load of ungrouped entries in my (frighteningly big) address book.

The logical thing would be to make a smart group for stuff that, say, isn't in a dumb group. But I couldn't see a smart group option for that. Any bright ideas?
