About 3 years ago in the UK, business people had Blackberrys and everyone else had Nokia or Sony Ericsson phones. Fast forward to now and business people have iPhones or Blackberrys while teenagers tend to use Blackberrys (they're cheap and good at messaging). Others have iPhones or Androids with the exception of people who haven't upgraded their phone in a while who still have Nokia or Sony Ericsson devices.
