irig/imic on macbook pro

[Muzik 4 Machines]

the macbook pro (new 2011) has this in the specs

Audio

Stereo speakers with subwoofers
Omnidirectional microphone (located under left speaker grille)
Audio line in minijack (digital/analog)
Audio line out/headphone minijack (digital/analog)
Support for Apple iPhone headset with microphone

so can one use the irig to connect a guitar or does the bass cutoff on the iphone (and the corrected curve IK probly has in it) will screw it up, cause it would be pretty nice to connect a guitar without having to lug a soundcard

EDIT: forget bout it, i googled after my post and there is like a gazilion hits

Yes it doesn't work on every model but the newer Macbook Pros and Mac mini's are working. If you have any specific questions about it working with your Mac hit me up here and I'll look it up for you guys.
