The listing for the Xperia P SmartDock has disappeared across all Sony Mobile language websites (a UK cache listing remains here). In addition to this, one user over at the Sony Mobile Talk forums reproduced some text with an online chat representative who had said the SmartDock had been cancelled. This would be a shame if true. We have asked Sony Mobile for a comment on this story but have not heard anything back so far. We’ll update this post if we have any confirmation one way or the other.
