Shielding an NRF24l01+PA

Someone had a tutorial on how to shield them to improve reliability and range. It involved wrapping the board with something non-conductive like tape or plastic wrap, and then wrapping tin foil over it making sure it didn't touch anything it shouldn't.
I've done this to mine, but, I have a question on grounding. The tutorial did not ground the shield. But, it's my understanding that shielding really only works when it's grounded. Can anyone confirm or deny this?

I've not written it, but the foil touches the ground on the antenna socket. So yes, it needs to be grounded.
In most cases it even works ungrounded though. Even a ungrounded shield has an effect on the circuit.
