Beginning on July 31st and ending on August 27th, Nintendo is giving players of Pokemon HeartGold and SoulSilver an item known as the Enigma Stone, which will allow players to catch either Latios in HeartGold or Latias in SoulSilver.
In order to access this WiFi Mystery Gift item you will need to have obtained the Pokedex in-game, and have fewer than two Wonder Cards saved on your game. Once you receive the Enigma Stone you must take it to Steven at the Museum of Science in Pewter City, and he will change the stone into a Soul Dew, which is a hold item that powers up the Special Attack and Special Defense of Latios or Latias. Upon leaving the museum you will encounter the Pokemon for your game, and it will be at level 40, so be ready!
