Hello. I am happy to inform you, that the Audio Input pins of the iPod Touch are active, and can be used for connecting any Audio source (like an external Mic, your CD-player, FM radio, etc) for recording. This also opens the doors for VoIP applications!! The way I tested it: Modded an old docking cable and connected the Line-In pins to a source of Audio signal. Then used the Voice recorder App originally written for the iPhone. The dock pinouts are here: http://ipodlinux.org/Dock_Connector I have photos of the setup if anybody is interested. Cheers!
