This HAS to the be the coolest use of technology i have seen in the past 6 months....
It is a service for Vodafone New Zealand customers that allows you to dial 808 and leave a voice message like....
“New contact... Juliette Stewart... Acme Cars... Manager... 021555555... fax 021555555"
Then ... beep beep ... an SMS arrives with a link to a .vsc VCard file that you cant download. If you are using a Windows Mobile Device you can simply click this link to download the card, open it and it will give you the option to add it to your contacts list! It also sends you an email with the VCard and a sound file with your original message.
How cool is that!
