It is region locked for iDS games. The iDS is region free for all original DS only games. Future DS games could be region locked on the iDS only, but I'm not sure. Obviously both the software and hardware have to support the region locking, hence why the old games are still region free on the iDS.
edit: obviously I posted really late.
As for the pokemon question, the answer is we don't know. They could region lock DS games and the DSi would not be able to play those imports. The DS which has no region locking wouldn't know any better and would play it fine.
But, I highly doubt it since it doesn't make much sense.
