Buried deep inside your computer's Intel chip is the MINIX operating system and a software stack, which includes networking and a web server.
Periodically, updated versions of firmware are available for free download.
If you need to reinstall the firmware to your Zune, you can do so with the Zune software for your computer.
Software updates need to be approved by mobile networks before your phone will allow you to update your software.
If you're using a phone that you didn't get from us, an update may not be available at the same time as it would be for a phone that came from Three.
After installing the Zune Software, plug the Windows Smartphone into your PC.
