Missing Icons in iOS 5

I have a new iPhone 4s and have a couple of issues I hope someone here knows how to correct....

1. I don't have the camera icon on the lock screen. I thought there was supposed to be button on the lock screen so you can immediately use the camera.
2. I'm missing the FaceTime icon on any of my screens. I have one on my iPad after the upgrade...should there be one on the iPhone?

Thanks for any help or suggestions!

Ok...after some more searching I found out I need to push the Home button twice to get the camera button.

And, I'm thinking the Facetime icon might be just on the iPad since there isn't a phone icon like on the iPhone.

The Face Time has always been in your call menu next to contacts with speaker phone
and mute .
