We're working with our friends at Vexed Digital on a unique experiment for Jameson to develop a mobile app which will help power the perfect night out in London and New York.

The app will ensure you visit exactly the right night spot, be it a bar, club or restaurant - think of it as a ‘social pulse’ of London and New York, personalised to you.

The beta trial is about to start but there's still time to be part of this unique experiment. If you're an iPhone user, socialise in London or New York and use 4square and/or Facebook Places then email us here.
