Three more days until the latest iPhone software release. Ever since the September release of firmware 2.1 there has been speculation of what features might be added to 2.2. Confirmed improvements mostly revolve around the maps application, including pedestrian and Google Transit directions, Street View, and location sharing.
Firmware 2.2 also includes improvements to the MobileSafari browser, support for audio input from third-party devices, and over-the-air (OTA) podcasts. Downloads of audio or video podcasts will be limited to 10MB file sizes when using 3G or EDGE, similar to app store downloads.
