How to disable album artwork on an iPhone (NOT remove)?

Yes, I know how to use Get Info and delete the artwork. But I don't want to delete it, I still want it to show up in iTunes when I use my computer. I remember in the past using an option on my iPod nano that allowed me to sync songs WITHOUT copying the art, in order to save space. Is there a similar option on the iPhone 4/ in iTunes 10, or has this setting gone defunct? (If so, we should really get Apple to bring it back, that was pretty useful)

No, if there was a way, I would use it too. If you jailbreak your iPhone, I'm sure you can find a way.
