well as far as i know this device is only available in japan i know of no reseller that sells this outside of japan
and there are some reports stating that the dev team of this "codefreak" (the name of this device) are going to make it work for newer CFWs
but as long as it is only available in japan it wont get us anywhere till we either are able to buy that or to get a hacked version of it that works without the dongle
