Finally Pokebank is in North America. We can now bring our Pokémon from Black/White and Black2/White2 to X and or Y.
Nintendo has released Pokémon Bank for North America today. This allows you to deposit, store and manage up to 3,000 Pokémon. You can download Pokémon Bank and Poké Transporter straight from the 3DS E-Shop for around 500 blocks on your SD card. A 30-day free trial is also available for awhile.
Also if you download the app by September 30 you can receive the adorable Celebi as a free gift. (Not sure how though lol)
