I don't know if it's device specific, or OS specific; but (and I hate to disagree with other posters) I don't think it's carrier specific.
I've been with my [same] carrier for probably 8 - 10 years and have gone through a dozen phones. On my last phone (Nokia E62) which I used until May 2007, I could turn on or off SMS delivery reciepts, and on my BB, I can't.
