I have a US version of the Lumia 800 that I purchased from Microsoft. It is unbranded and unlocked (like all of them purchased through MS), but my service is through AT&T. I've been reading about the Tango and firmware update that is being rolled out around the world and it all seems to be carrier driven. But when I read about Tango updates coming out in the US, the carriers are only talking about updating phones issued through them. For example, AT&T recently announced updates for the Lumia 900, but not a peep on the 800.
My guess is that 99% of Lumia 800s in the US use AT&T's network, but AT&T barely acknowledges its existence. Evidence of this is that after several months of ownership, my phone still doesn't register on its billing system as a Lumia 800.
So, to my question...Since I don't have an AT&T branded phone, who will be rolling out my Tango/firmware update? AT&T? Microsoft? Nokia? Does anyone have any insight into this whole thing?
