My friend on Final Fantasy XI, Iyaka, traded me an Arceus that she got from the 12th Movie in Japan. This happened awhile ago and I tried posting this "proof" on the Serebii Forums, but the mods are a bunch of snobs and they have to approve of threads before posting it, so...
Anyways, this totally confirms that the 12th Movie Arceus CAN unlock the Hiker event in Platinum, which leads me to believe that the Japanese Arceus can also be used in the English HeartGold and SoulSilver games as well.

These are the pictures I took with my DSi to my DSLite having the Platinum game in it.












Obviously this even continues in the Canalave Library with the same Hiker. And looking at the link from Serebii.net, the translation they have from the Japanese Platinum is a direct translation of the one in the English! I was quite shocked when I saw that. Oh, and I traded a Slowpoke from Pearl, in case you were wondering. I only have 5 Badges so far.
So what does everyone else think? I think my friend Iyaka had soft-resetted with that Green Delivery Man in a Poke Mart to get that nature. I tried the IV Calculator on Serebii's website and it's a legit one, but I don't think my friend Iyaka would hack something like this.
