Yepp, same thing happened to me. Luckily i only had to merge about 50 contacts, i'm not that well-known ;-)

But its a pain in the butt, you're right. And its not a bug at all (at least not of our phone).

Worst thing is, that i really try to keep my contact list tidy, and this sort of things messes everything up.

Well, i think we'll have to live with it...
