Yes, Kaitou KID does know in the anime/manga series. In volume 30 (Episode 219), he calls Conan and Ran the "Two lovers you don't want to meet," meaning he knows that Conan is Shinichi. He probably said that because their love can do anything (even kill someone maybe!!!

), and also because their relationship is so similar to him and Aoko's...
That's my theory, but I'm pretty certain KID knows about Conan in the actual series.
Okay, reviving this thread here...
ANYWAY, I take back what I said up there^.
Reason being, I found Aoyama-sensei's own English translation of those lines, and it turns out he was refferring to Kaito and Conan... (Yes, his English grammar isn't very good, but forgive him... He's good enough writing DC for us!)
"Who is that guy?"
"Huh, he is a sort of sweetheart i want to avoid..."

But I'm still sticking with the belief that Kaito knows about Conan. Any genius like Kaito would immediately find it suspicious that a 7 year old kid has enough intellect to figure out all his tricks and nearly catch him all the time.
