Will updating to iOS 6 delete everything?

Will updating to iOS 6 delete everything on my iPhone 4S and iPad 3 if I do it over the air?

No. The update will be painless.

I assume not. It's been some time since I've had to upgrade a phone but I'm almost certain that everything (apps, contacts, messages, etc.) will be untouched.

It shouldn't delete anything if you do the OTA update, but you should still back up your important data, just in case.
