In my thread, Rongzhong Li (Admin) answered, maybe that helps: We are building a new homepage with an online store. It's 80% done and will provide options for the accessories. Because I cannot seem to find the (by now apparantly included) bluetooth-dongle for sail in the typical shops as well.

Hmm, that kinda sucks. xD I was expecting for it to ship with bluetooth-capability. Oh, well... thx for the answer. Ps. Might be a good idea to mention that in the manual tho
