It’s a bit of a weird party – members of the German press are given a new Windows Phone 7.5 and invited to run around an old hotel. Scattered throughout are actors playing out parts of Ghostbusters (some more successfully than others), Q-codes that link to information ab out the phones and the ghost haunting the hotel, and special rooms where they can use the phones to spot the ghosts (as well as get slimed by them.) One can only assume that some official agreement was in place, given the clear use of the GB logo (not to mention Slimer.) Or may not – either way, cool way to promote a phone. Very reminiscent of the Ghostbusters Secret Cinema in the UK from a few years back.
