The World Health Organisation have added internet-enabled mobile phones such as the iPhone 4 to their register of substances and activities that may result in a broken nose.
A spokesman said "users of these devices may find that they suddenly have access to answers for most pub questions and arguments, and are often tempted to share this information. This is what we believe leads to most of the fractures." Other fractures are thought to result from incessant tweeting.
One consumer is considering suing provider O2, whom he alleges caused him to get "a smack in the mouth" for insisting on photographing every object in his house over a two-week period using Google's 'Goggles' application "to see what would happen". He reports that most of the results were "similar" pictures of objects the same colour as the one he photographed.
The only known way to make these devices safe is to move to the countryside or switch to Three, although even this is ineffective against the more resistant "Angry Birds" strain.
