Yahoo has built a number of applications for the iPhone (and even a custom one for the iPad already), but with all the buzz about location-aware services they haven't yet felt the urge to optimize its own Upcoming service for the mobile platform. Enter developer Nik Fletcher , who has spent about a year developing one dubbed Happening to "scratch his own itch". Version 1.2 is available in the App Store right now ( iTunes link ). It's essentially the Upcoming app Yahoo should have built - and at the very least they should have made it easier for the man to develop it for them.
