iPad Headphone Jack - Mic Capable (TRRS) like iPhone?

Wondering of the headphone jack is mic capable (TRRS jack like the iPhone and newer Touch) or just TRS like the old Touch and older iPods...

Anyone know?

"The iPod uses a TRS connector while the iPhone uses a TRRS connector for its headset (microphone and control button). Newer models of the iPod now also use TRRS connectors."
