iPhone 4S support HE-AAC V2?

Does the iPhone 4S support playback of Version 2 of HE-AAC (parametric)? I have a ton of music to convert from lossless to AAC, but I want to make sure the phone will actually playback the format properly. How about version 1?

This is a little late, but I stumbled across this today without being able to find a definitive answer elsewhere.

As of iOS 6.1.3, the v2 HE-AAC encoder with Parametric Stereo is not supported. Playing back those files results in mono output.
