T-Mobile Selling iPhone Accessories. Why?

This one is an interesting find by our Engadget friends. Apparently some T-Mobile stores in the US are selling iPhone charging cables. What can that mean? Are they preparing for the T-Mobile iPhone? We’ve heard our share of rumors about that in the past.

Or maybe they’re just trying to provide accessories for iPhone unlockers who make the move to T-Mobile? Your guess is as good as mine.
