It's a bloody phone
All it needs to do is go brring brrring
When the things ring(*) people tend to answer the call not sit there listening to a tune, all a waste of time and money in my book.
(*) Can you still say a phone rings? What should we say when it's the dambusters theme for example.
This is a totally impartial comment as I don't have a mobile phone, although if I did and it played the dambusters theme I reckon I would listen to that rather than talk to anybody who'd want to call me.
