The software update is delivered though the Zune Desktop client. When the update is available for your device you will receive notification via an on-screen pop up message. You can also perform a manual check for updates in the Zune Desktop client (phone > settings > update).
While the update is now widely available, it is not universally available. This is because software updates must go through an approval process (testing and certification) before being released. Nokia's software update page has information on availability by country and product code. It is the product code that determines whether an update will be available; you can find your phone's product code on a sticker underneath the battery (Nokia Lumia 710), or under the SIM card caddy (Nokia Lumia 800).
