Original iPod touch owners on Tuesday night got first crack at the 2.1 feature set with Apple's promised firmware update for first-generation players.
The update is
available through iTunes and adds many of the new features present in the
second-generation iPod touch that aren't dictated by hardware choices.
This includes the Genius feature for automatically creating a playlist of related music, software-related optimizations to battery life, and a host of additional fixes and other adjustments.
Apple hasn't posted a full list of updates.
As promised, the software is a free upgrade for any iPod touch owner already using version 2.0 firmware or later; those using any version 1 software must pay $9.99 to unlock and download the 2.1 update.
The version 2.1 update for iPhone and iPhone 3G users will be free but will appear slightly later, launching on Friday.
