iPhone OS 2.2 Beta 2 Released: Adds Support for Audio-In; VOIP for iPod touch?

Apple has released a new beta of iPhone OS 2.2 to developers. The new release adds support for audio-in devices in all third-party applications, meaning apps will be able to receive audio input on all devices and possible paving the way for genuine VOIP applications for the iPod touch.

The new release also re-adds APIs that may be used for live-updating (true GPS-like) directions in the Google Maps application--course, speed, direction etc.
