Charlie Fish: (retrieves) With social mobility at an all-time high, our sense of a loyalty to a tightly-knit local community is often completely destroyed. Instead, we are dispersed, moving home and job more frequently, going on holiday to different places every time, commuting further... But mobile phones allow us to retrieve this sense of community. Suddenly, everyone is on our doorstep. If you doubt that statement, speak to someone who has lost their mobile phone and they will tell you that being without their contacts is a lost and lonely place to be.
