An interesting article from the BBC says that in the U.K. people are becoming so dependent on their mobile phones that one in three are concerned that losing their phone would mean they lose their friends. The survey on which the story is based shows the extent to which people have become reliant on their phones as address books. More than 50% of mobile owners reported they had had their phone stolen or lost in the last three years. More than half (54%) of those asked in a poll for mobile firm Intervoice said that they do not have another address book. A fifth rely entirely on mobiles. About 80% of UK adults own at least one mobile, according to official figures. It is estimated that 53% of over 65s own a mobile, according to Intervoice, but the figures are higher for those aged between 15 and 34. Most 15 to 24-year-olds (94%), and 25 to 34-year-olds (92%), own at least one. Nineteen percent of mobile owners were more concerned about how long it would take to find their contacts' information again if the phone was lost, stolen or replaced.
