Yes but not with the GSM IC - the Neo1973 itself has a quite powerfull

Of course ;) we had already several normal or freaky ideas what
to do with it. Sorry that not every idea is in our wiki yet..
but we have our mailarchive.

Just see the Neo as a 
mobil (embedded) computer + Linux + GSM/GPRS + AGPS + Bluetooth

Have you had something special in mind to do with the audio IC?
