the only one i know for shure is the V3. it can be debugged, but i don't recommend it because you won't get to put in a username wich means that you won't be able to use any password from tama town, or get to have any souvenirs in your list, or get to get souvenirs from your plane trips.
I haven't checked my mini to see if it can be debugged, and i won't receive my V1 until the end of the week.
