Well the iPhone 5 does not exist at this point, and the iPhone 4 is the only iPhone with a flash- so it will only be on the iPhone 4 (and it's succeeder, when it comes out).
In the keynote video at 1:16:45 in the bottom right corner "LED flash for incoming calls and alerts" is listed as new feature.
Is this for iPhone 5 only or also for the older models ?

I don't think that they will use the camera flash for it.

Accessibility
iOS 5 comes with innovative new features that make it easier for people with mobility, hearing, vision, and cognitive disabilities to get the most from their iOS devices. iOS 5 works with specialized hardware accessories. The LED flash and custom vibration settings let you see and feel when someones calling. And improvements to VoiceOver include custom element labeling. These are just a few of the ways iOS 5 continues making advances in the field of accessibility.
