I know that my 5.5G and NanoIII can take microphones (I use them to record classes) so there is probably circuitry to get sound into the Touch, yes? Is there any way yet to use a Touch as a Wifi phone? Skype? Other? If there is, and if I can also use it to browse and do mail, I may just keep my 6300 as a pay as you go and use the Touch whenever Wifi is around.
