Something else, Greg. Are you aware of any 3G / 2.5G (EDGE) clients for
mobile phones that support AAC+ streaming? Be it java or symbian based.

I believe that Oddsock is using a Content Type of aacp.
Using a .aac extension with this Content Type may present a conflict.
This might actually be by design.
I will do some further testing with Winamp and report here tomorrow.
I will also double-check with the developer of Winamp for complete

FYI, Orban Opticodec-PC allows the use of either Content Type of aac or
aacp. aac is technically all that is necessary. The history of the aacp
Content Type was to allow the stream to show in the SHOUTcast Directory, but
since Icecast streams cannot show in the SHOUTcast Directory anyway, this
doesn't matter, and  a content type of aac should be used. This way there is
one Content Type for either AAC or aacPlus streams, and the decoder takes it
from there.
