Yes but as some articles have stated, that's a hack that works and we don't know if Apple would disable this. As we know, the same connector doesn't allow that same feature on the iPhone so we know it can be locked out.
The official Apple endorsed method (eg using a Cypher Solo DAC type device or a digital dock like the Wadia) is still limited to 44/48kHz IIRC
