Hi there
Yes, it is possible to update.
But you will have to wait for your telco to take turn. The updates are not rolling out for everyone in the same time. It goes by regions. It might be many weeks for you to get it, even tho some near to you countries are getting it already. In here, Malaysia, we get updates fairly fast because all units are unlocked, even the one on contracts from telco comes untouched with telco's bloatware or modifications of any kind.
