Forum user pismodude2 was able to confirm that the 2nd generation iPod Touch will allow microphone input and work with existing microphone-enabled applications. He was able to use a 3rd party microphone headset to input audio into his new iPod Touch.

We had previously reported that Apple's new microphone headsets were listed to be compatible with the 2nd Generation iPod Touch, although we had initially expressed some skepticism as this feature was not listed in any other location.

Allowing users to conveniently add an external microphone to the iPod touch opens up the possibility of using the iPod Touch as a telephone over Wi-Fi connections (VOIP).
