So it looks like the Lumia 920 will be exclusive to At&t for 6months,
According to training videos for the Nokia Lumia 920, WPCentral obtained from their At&t sources, the Lumia 920 will be exclusive for a limited time of 6months.
In the first video, you see a pop-up, which shows the message that the Lumia 920 will be exclusive for 6months.
So the question is, will it even matter anymore after 6months? we live in a smartphone era where phones become obsolete just 6months from their first release. So, will verizon subscribers will yearn for the Lumia 920 6months from now? will T-Mobile users still be anxious to get one in May, 2013?
It will be amazing to see how other mobile subscribers (other than at&t) react to a "no longer" exclusive Lumia 920.
I think it will all depend on how well the Lumia 920 is received first of all on the at&t network, remember this is how the iPhone started, though it took them 5yrs to build that reputation. this will only be Nokia's 2nd year in the windows phone space. (truly their first if you ask me).
My conclusion, 6 months from now, it will hardly matter (though I would love to be proven wrong), think about it, 6 months from now, we will be talking SGS4, new motorola droid phones with 32 core processors and not to mention rumours of the iPhone6, oh and lest I forget, a 920 successor?!
