My company just launched a free public beta for a Location Based application called TagandScan. TagandScan is a service for your mobile phone that enables you to mark real physical locations with an electronic tag. Tags automatically contain the time and location where and when the tag was made. They also can contain a title, description, and a photo.
We really need some tech-savvy mobile users to play with the application for a while. All you need is a Java enabled phone and to use T-Mobile, Vodafone, O2, or Orange in the UK. To sign up, go to www.tagandscan.com. Happy Tagging!
