you have the Tango update already, the lumia 900 comes with it out of box.

i was referring to the lumia 710 and 800 users

could be marketplace region settings? its only supposed to be out for China and US marketplace...

same for lumia 710

i tried US, singapore and now Malaysia all no update found...

when WIFI is on, search for the update. Time how long it takes for it to say that your version is up to date.

Then try again, you have to turn off your WIFI just 1 or 2 seconds before you get the 'your version is up to date' message.

once that works and it says that there is a update available then only turn your wifi back on, so you can download the new update



hope that helps
