It's aftermarket and made by a company called TH Bury. It's actually quite a good kit because you can buy cradles for most popular phones and they just slide into place.
Can you tell what I do for a living?
mail my colleague Scott to sales@freedom-mobiles.co.uk and he'll get you a price for the cradle. The 6300 is quite new though so you may have to wait for THB to launch a cradle. (if in fcat they do at all). Nokia themselves don't make a cradle for the 6300 and it has not clip points anywhere on it. They recommend using a full bluetooth kit for that phone so maybe you'll need to change your phone as well.
