As you would expect,  I look out for Vodafone related stuff on the web and one of my friends on twitter (@russelljfkirk) pointed me in the direction of this video - http://www.mobilebehavior.com/2009/10/26/vodafone-demonstrates-innovation-using-1000-mobile-phones/.

With all of the free texts you get these days from mobile operators,  this might be one way to make sure you get the most out of them :-).

Finally if you look further down the page you will see a converted phone booth .... nice :-)
