The SMARTLocator.TAXI application from E-Taxis.com has been released in Beta form for testing. It uses GPS (free, if available) or ‘mobile triangulation’ (20 pence per request) to find the telephone number of the nearest taxi service to your current location. You can then call them and request a pick-up. It works anywhere in the UK, and runs on any Microsoft Windows Mobile 2003 SmartPhone.
If you live in the UK, have an MS SmartPhone, and have tried out this application, please post your thoughts below in the comments. Did it work properly? How long does it take to give you the phone number? Would you pay for such an app?
I wonder if the GPS is autonomous, or assisted.
