The Nokia Lumia 900 is rolling out around the world at present, and the latest to carrier to reveal their hand is Tele2 in Sweden.
There the Nokia Lumia 900 will be arriving, provisionally, on the 11th June and will be free on a 289 Kr/month contract.
The handset is currently available in UK already, with the major delay appearing to be the popularity of the handset in the USA.
