Pokemon HeartGold and SoulSilver versions

Sorry for not posting in forever. Internet was down. Anyway, Pokemon HeartGold and Soulsilver came out recently. As I understand it, you can do almost anything with the touch screen. From moving pokemon from box to box to choosing items in your bag. We see Team Rocket this time around (ah, good old Team Rocket), and what they're up to is...well, not good. Duh. Anyone who is familiar with the original Gold and Silver versions have an idea of how the game flows and what Pokemon can be found. Also, I have heard if you send Pokemon such as Arceus, the recent Jirachi, and the Pikachu colored Pichu from Diamond, Pearl, or Platinum into Heartgold or Soulsilver, some secrets are unlocked. I can't tell you what kind of secrets though...:)
