The update will be available for your unlocked phones depending on your location. So if you want to install the update, you need to connect your phone to Zune Software and then check for updates.

This will prompt you to select the languages. Please note you need to select all the languages which are currently available on your phone. Click on OK. Now your phone will reboot an will start installing the update. On the phone you will see a white progress bar indicating the installation of updates.
Once the installation is complete, you will see the phone booting again with the sucess message of installation of updates. Please note if you have not updated the phone for quite some time, you will have to install all the previous updates before you can get WP7.8. So you might have to follow this procedure multiple times.
