Pokémon Black and White Cloning Glitch

Описание: Edit: Unfortunately this no longer works due to Nintendo closing the wifi for Nintendo DS Games.

A cloning glitch I discovered accidently a few months ago. I explored the idea and have since been able to successfully clone without external devices.
You do not require any Pokécheck services. You just need to be able to connect momentarily. THEY WILL NOT GET RIBBONS!
Pokécheck: http://www.pokecheck.org/

Requirements:
*Wi-fi connection
*2 Pokémon games of the same Gen
*A Pokémon

1. Deposit a Pokémon on the GTS.
2. Change your primary DNS to that of the Pokécheck GTS (087.098.141.099).
3. Connect to the pokécheck GTS. The Pokémon you offered on the real GTS will return to your box.
4. Boot up your second DS. Change your Primary DNS to auto. Go on the official GTS. Find your offer and trade with it.
5. You now have the Pokémon you offered on both games.
6. Go on the first game and connect to the official GTS. You will recieve the Pokémon you traded from the other game.

For DSis:
1. Go to System Settings.
2. Click Internet, then Change Settings.
3. Click 'no' for 'Auto-Obtain DNS'.
4. Change the DNS to 091.121.021.220

Btw I do not own Pokémon.
