Put a couple on the wrong thread.

Layar : Funky augmented reality app, taps into various resources to show you places of interest around you with little dots on your camera screen. 3GS

Cyclopedia : Same as above really, but only uses wikipedia as a source, so not quite as good. 3GS

Mobility Finder : Find your nearest mobility car, bit basic at the moment, it only finds the nearest cars and then has a button to phone mobility themselves, but if they keep developing it to make it something like the SBB app, it would be fantastic.
