I would too scrapple but i don't think ATT will do it. They might say more about it at the conference in Europe later this month though. Come on 3-18. I want my 900!!
It has been a while since AT&T has landed a Nokia device, and it might be played close to the chest upon releasing, meaning AT&T (site and store) might be the only ones to offer it until ship date. AT&T could very well have a pre-order page soon. If you go to nokiausa.com You can sign up to be notified when the Lumia 900 will be available.
