Question: I need to live-demo a Mobile Safari browser app (iOS 5, iPhone 4S) on my Macbook and was wondering the best way to do this?

One way I thought might be possible would be using AirPlay Mirroring, but there doesn't seem to be any Mac OS apps capable of showing my iPhone screen mirrored.

I am an (beginner) iOS developer and wondered if there was anyway I could knock up a basic app with a UIWebView in it to somehow stream the contents of the web page and my interactions with it to my Mac.

Any thoughts?

*EDIT*: Yes I know I could use the iPhone Simulator, but I need to interact with it on the handset using the mobile phone network.

Answer: 
Since your device (iPhone 4s) supports video mirroring via AirPlay, then you should be able to use [AirServer](http://www.airserverapp.com/) to enable mirroring to your Mac.

Update: As pointed out by Marc Surman, AirServer does not support mirroring, rendering this answer incorrect. Thanks for playing.
Mirroring uses FairPlay encryption, which is why AirServer and similar applications can't do mirroring.

You CAN, however, fake this using AirplayKit:

The iOS demo in that repo actually does a simple mirror by sending an image of your screen to the airplay device using a timer. It would probably work just fine for a demo, and should work with AirServer.
