iPhone SDK 4.0 Phone locked tool

Is there going to be a way with the 4.0 SDK to create a t开发者_运维问答ool similar to Pandora(which was demoed today), so when the phone is locked, I can manipulate my app? So basically if my app was running, and my phone locks I don't have to unlock the phone to toggle something for the app?

As kubi said, it's still under NDA. I would look into those API's that were publicly announced though. (The multitasking stuff.) I'm sure it's possible. Pandora did it in the demo, right?
