A supposed earlier correspondence between Microsoft's Joe Belfiore and Aamer Khan denoting "problems" with the Lumia 900 is evidently erroneous.
Belfiore has sent out a Tweet, in response to our own Rafael Rivera, noting that the account referred to in our earlier post is in fact a fake:
Any alleged FACEBOOK message from me that claims anything is wrong with Lumia 900 ... also a fake. :)
The Lumia 900 is a Nokia phone in AT&T stores.. the launch date is Nok + AT&T's news to announce. Not us MS folks. Sorry!
So while we still don't have a Lumia 900 on AT&T and no firm date is in place, let it be known, we now know nothing more nor nothing less than a few hours ago.
