This was the first firmware released for the Zune line which did not provide new features for older Zune models.
These models were given a firmware update with version 3.2. This update introduced Smart DJ and codec features.
Zune included a line of portable media players, digital media player software for Windows PCs, a music subscription service known as a "Zune Music Pass", music and video streaming services for the Xbox 360 game console via the Zune Software, music, TV and movie sales, and desktop sync software for Windows Phone.
It automatically fixed itself 24 hours later, but an intermediate "fix", for those who did not wish to wait, was to drain the device's battery and then recharge after 12 noon GMT on January 1, 2009.
The first generation and later Zune devices included a number of social features, including the ability to share songs with other Zune users wirelessly.
A firmware update brought picks and an improved the TV-out experience to the Zune HD.
On March 15, 2011, Microsoft announced that no new Zune hardware players would be developed, although existing models would remain for sale.
The 4 and 8 GB Zune devices use flash memory and are smaller in size than the 80 GB version, which uses a hard drive.
