I had looked at this earlier in the week, but due to a lack of time, wasn’t able to cover it until now. Apologies.
Nokia is preparing the 8779 Tango update for Lumia 900 owners in North America (AT&T & Rogers branded). Navifirm confirms the update, so the roll out should be just around the corner.
Nokia’s servers are displaying the updates as 2175.2301.8779.12222 for Rogers and 2175.2301.8779.12223 for AT&T.
This is good news for the North American Lumia 900 owners who seem to be long overdue for the update.
Cheers if anyone tipped it.
