Windows Phone application state after sleep and/or lock

Question

I developed a Windows Phone 7.1 Application, everything works well and I'm very happy with it. Although... Having the phone fall asleep while the app is running or locking the phone while still in the app, and then unlocking/waking up the phone - The app closes and I have to relaunch it.

So this then comes down to how your app reacts from a sleep state. How does one handle this event and just let the app continue where it left off rather than closing the app and having to manually re-launch it?

It would also be great if at "PhoneWake" or whatever you'll call it I can run a few functions before the app continues.

Thanks in advance!
