How to get an iPhone to automatically add an apostrophe

This is similar to the "." Shortcut. If you make sure to turn the shortcut on in Settings->General->Keyboard, the keyboard will add a period to the end of a sentence and engage the shift key every time you double-space. It's a minor convenience, but makes text entry a little smoother, and every little bit counts when you're using a virtual keyboard.

What apps does this trick work in? So far not the calendar or notepad or email or Safari.

double spacing ... isn't that a major hangover from the days of using typewriters? You still see it in some writings because once you have been taught to touch type it is very hard to break the discipline drummed into you by rote learning.

Still I guess it's then easy to hit the delete/backspace button

Slightly off topic - I still find the iPhone virtual keypad a pain to use when dealing with numbers, especially when everyone encourages you to use numbers, letters and other characters in passwords theses days.
