AAC+ support wasn't implemented until version 2.2 of the iPhone OS.
The support for AAC+ is backward compatible only in the sense that you
may *compile* to 2.0 and still get AAC+ support, but you must *run*
the app on 2.2 for AAC+ to work. You can check the list of available
codecs on the current device by calling AudioFormatGetPropertyInfo for
property kAudioFormatProperty_DecodeFormatIDs.
