Presently, the two versions of Lumia series that have been launched already in Australia are Lumia 710 & 800. And now, Nokia is all set to launch Lumia 900 & 610 in the country.
Nokia is launching these two handsets as press invitations for an event to take place in Sydney. The event will take place on May 17th. Assuming that the phone will be displayed over there, we can say that it would be officially launched around the mid of June this year.
Right now, there isn’t any other info out related to this launch. The only doubt that many have is if these two devices would be 4G LTE phones as they are in the United States. If not, they are expected to be the international version-handsets supporting HSPDA+ DC.
