A recent post on The Mac Observer pointed out a useful way to set alerts on an iPhone. If you dig deep into the ACcessibility settings (Settings > General > Accessibility), in the Hearing section, you'll find an option called LED Flash for Alerts. If you turn this on, you'll get a flash whenever you get an alert, such as for phone calls, text messages, etc. This is most useful if you're in a situation where you need to turn the sound off on your iPhone, or if you're in a noisy environment, and may not hear any alert sounds.
[kirkmc adds: This only works if the iPhone is asleep; in other words, if the screen has gone dark. It would be helpful if it flashed in all cases. Also, if you have the iPhone on a table with the LED on the bottom, you may not see the flash.]
