smart2go

From gate5 - can this be classed as a location-based tourism application like Timespots?

smart2go™ turns your mobile phone (Symbian Series 60, Series 80 and Microsoft Windows Mobile Smartphone), PocketPC or Palm into a full scale navigation system. Navigate easily with clear voice commands in 5 languages. Enjoy the added value of premium guides providing restaurants, cafés, W-LAN hotspots or hotels, all detailed in your map data.

Not sure if this has a P2P/collaborative component though... For some reason, hearing about the more social-network-esque services seem more exciting, in an 'empowered consumer' & 'co-creation of value' kind of way. =)
