The Telegraph has published a 10-point guide to cell phone manners from Debrett's, the traditional authority on British aristocracy and social manners. The kinds of things you'd expect, like:
8. Step away from the phone at meal times
Don't put your phone on the dining table, or glance at it longingly mid-conversation.
9. Don't carry on mobile phone calls when in the middle of something else
Don't carry on mobile phone calls while transacting other business - in banks, shops, on buses and so on. It is insulting not to give people who are serving you your full attention.
Most of it is intuitive, meaning the people who will read it don't need to be told how to take calls or not in various situations. And as commenters at Metafilter quickly pointed out, the list is only about phone calls, which is inadequate in an age when young people use smart phones for much more, like texting, watching TV, web browsing, music, and social networking. If we were going to construct a comprehensive list of rules for using smartphones, what rules would you suggest? Link
