On my unlocked HTC 8x shipped from Hong Kong , there were two updates, the Portico(8.0.10211.204) and another nameless HTC update. GDR 2 did not appear. Go ahead and download. Before installing check the update information. You can always postpone the update if its GDR2( 8.0.10327.77). The Portico update is really essential as I found it improved the idle battery life substantially.
