INSTALL:Launched this week in Dublin and Cork, iCabbi.com is a virtual taxi dispatch firm that allows you to book taxis

from a smartphone app. It uses the location capability of your phone to send the taxi to your current location, and once you make the booking you can track your taxi’s progress to your location in real time. To make the service more secure for

solo travellers the details of the car and driver are sent to your mobile phone and two nominated e-mail addresses.

Currently the app is available for the iPhone.
