Oh my god, yesterday, the exact same thing happened to my iBook adapter connector...
My cat was just running around (I swear, that creature has ADHD or somtething) and it ran so fast around me, sitting in my bed working on my iBook, that it somehow caught the cable, yanked the cable out, and ran out.
Looking at the connector, the round metal part was severley bent, so was the gold jack in the middle. The round part I managed to straighten out, but when I tried to do the same thing with the golden jack, it snapped off

. All in all, it was in a much worse state than the one pictured in the original post.
Now I live in [location on the left part of the screen], where the service at the first opened Apple reseller is horrible, I even made a previous thread and people were appaled.
Well, I discovered a new Apple Authorized reseller & Tech opened in town, went to them, and was pretty satisfied. I just got a call from them and they told me they'll have to use third party components for the repair. And there's a possibility they won't be able to repair it, so maybe I'll have to buy a new adapter.
Gawd... what's next? Ritalin for kitties?
