Do you want to know a secret?

We're not very bright when talking business on our mobile phones. That seems to be the message from Vodafone, which says indiscreet mobile conversations are a threat to company security. More than 70% of all employees talk about business on their mobile phones in public, with 15% discussing confidential new products or services. Worse still, 26% confessed to following up on a lead they'd overheard in someone else's phone conversation. Vodafone suggests using more discrete methods of communication, such as text or mobile email, when on the move. It's promoting a collaboration with Virgin Trains that provides improved 2G and 3G mobile phone coverage within Virgin's high-speed Pendolino trains between London and Glasgow. [Press release]
