Using iPhone in cold 'risks RSI'

The iPhone: unsual finger movements?iPhone

Buying an iPhone may not just cause serious injury to your wallet.

The £270 device could also leave users with repetitive strain injury, it is claimed.

Flicking through menus, text messages and photos risks cutting the blood supply to finger muscles – especially in cold weather, experts warned.

And overuse of the Apple gadget could even damage the whole arm.

Despite its hefty price-tag, the iPhone sold 1.4million units in its first 90 days and was released in Britain last month. Its combination of phone, music player, Web browser and camera have made it the must-have gadget this Christmas.
