Can I turn OFF display of Video PodCast...?

[A.C.Fairbanks]

Howdy,

Is it possible to turn OFF the display when running a video podcast, so that I can listen to the audio without depleting the phone's battery?

If so, how is it done?

(I know it could be done on earlier iPhones...)

Thanks for any help on this,

A.C.

??? Even with a jailbreak iPhone I don't see a way for doing it.
