As with all android phones, you have to be running stock for you to receive the OTA update. If you are, when its released, its done so in stages. They select batches of phones to release to alittle at a time slowly making larger batches each turn until its all out there. You will receive a notification of the update when its ready. Sometimes there are ways to make the phone check in manually, but if you aren't up on the list yet, it wont do you any good. So just wait and be patient. It will happen when its ready to happen and not a moment sooner.
