Found topic in DF. Don't feel like finding the link that was posted. But it works, I has mew!
While the rest of you suckers are going to be running around, perfectly content with your housetrained Mewtwos, we're going to take advantage of an upcoming promotion from Nintendo -- one which allows us to come face to face with the original event Pokémon: Mew. You too can lock down Number 151 by using the Mystery Gift option on your copy of Pokémon HeartGold or SoulSilver from October 15 until October 30.
The Mew you'll receive is only Level 5, meaning the world's your oyster when it comes to how you decide to raise the little guy. We're unsure of where we'd like to focus his stats, but we are certain that we're going to name him Joey, and make him wear a little baseball cap, and he will be our precious little perfect angel.

RETURN TO THE JOHTO REGION AND DISCOVER THE HIDDEN POKÉMON THAT STARTED IT ALL – MEW
Pokémon and Nintendo Offer Limited Distribution
To Celebrate Tenth Anniversary of Pokémon Gold Version and Pokémon Silver Version
BELLEVUE, Wash.-October 12, 2010-It has been 10 years since Pokémon fans first visited the Johto region in the Pokémon Gold Version and Pokémon Silver Version video games. To commemorate this historic occasion, Pokémon Trainers can get the Rare Psychic-type Pokémon Mew for the original titles' remakes, Pokémon HeartGold Version or Pokémon SoulSilver Version, for the Nintendo DS family of systems via a Nintendo Wi-Fi Connection distribution event October 15 through October 30, 2010.
At first, it was believed that there were only 150 Pokémon. As #151 in the National Pokédex, Mew was the original secret Pokémon, revealed for the Pokémon Red Version and Pokémon Blue Version video games. Over the past 12 years, Mew has very rarely been attainable, making this an extraordinary opportunity for Trainers across the nation.
The Mew character you will receive is a Level 5 and comes with one basic Normal-type attack, Pound, giving Pokémon Trainers the ability to raise and train Mew as they see fit. Making this distribution especially exclusive, Mew comes inside a Cherish Ball and has a Premier Ribbon, both indicating that you got it via a special event.
During the limited distribution period, players will need to receive Mew using the Mystery Gift option via the Nintendo Wi-Fi Connection service and their existing wireless broadband Internet access, and will need to acquire the Pokédex in the game. Players must also have fewer than three Wonder Cards in their game.
This historic distribution event is only available for a limited time.
