The availability of an update for your phone depends on the region and carrier. Also, you should try updating using PC Companion or Sony Update Service, as the update is too large to be performed over the air.
I did update my Z1 over the air, it's now 4.3, it takes less than 5 minutes but eats up 40+% of my battery(not sure if it's a bug or what), luckily i have 70% battery before update.
