|Get this as a Wallpaper too!|
This already started on May 9th, but you have until June 10th to download. As noted above, you can now get your own copy of Darkrai if you have either the Black or White version of Pokemon for the DS, DSi or DSi XL.
The best part is you can do this anywhere there is a Wi-Fi connection and link up with Nintendo. No going to a damn store and have the hassle of sales people bugging ya to get something.
For more information on getting this, check out Pokemon.com.
I did get this for my son as his game is currently taken away. Caught him playing with his DSi in bed after her was suppose to be asleep!
