AT&T is planning on October 21 to launch the Lumia 920

The technology site BGR has recently said Sunday October 21 is the release date Nokia Lumia 920. At that time, we have underestimated the rumors because there is no official information what WP8 as well as messages from Nokia.

However, the WPCentral consulted a number of new materials for circulation of AT&T, has actually confirmed October 21 is an important day for the next top phone of Nokia. The language in the documentation clearly uses the word "launch" when discussing the Lumia 920, however there are mitigating circumstances that still makes it hard for us to believe. If we had to play it conservatively, we still may be getting the preorder date.

Unfortunately, due to our agreement with our source, we cannot share the contents of the message/documentation nor whom it was from, but be assured that we know that information and we are confident in its accuracy. Our source of the internal AT&T material had earlier confirmed the Mango-update dates for Windows Phone, which turned out to be very accurate. For that reason, we impart a high level of trust in this knowledge.

We still have reservations about this date only because Microsoft is reportedly not set to unveil all of Windows Phone 8 until the end of October and most OEMs we have spoken with are sticking with their “early November” timeframe for release of new hardware. Just as we originally reported, that gives us pause.

However, if Microsoft could launch sooner, maybe the game will be even more interesting when Apple going to bring the iPhone 5 to consumers. 

Can Microsoft and Nokia (and AT & T) do to surprise us? Let's wait and see.
