I switch on the messaging feature on my phone when I am in a meeting Men tend to like smaller mobile phones while women prefer larger ones. Mobile phone bores leave their phones on all the time and use loud and annoying ring tones. Mobile phone etiquette involves using your mobile phone in a way that does not annoy other people. Other people's bad mobile manners are driving me mad! Being a smart mobile phone user means using a'hands-free' phone in the car, speaking quietly in public etc It is a revolutionary phone that fits neatly in your pocket.
