Though it officially launches in AT&T stores this coming Sunday, April 8th, the Lumia 900 was up for pre-order late last month — and we now have word from users in our forums that the phone is starting to show up. The 4.3-inch, LTE-enabled Windows Phone is an extraordinarily big deal for Microsoft and Nokia alike: Redmond is awaiting its first runaway blockbuster success for the platform here in the US, and Nokia is looking to make a smooth transition away from Symbian with as little pain as possible. AT&T appears to be taking the 900 pretty seriously, too — the carrier calls it "the smartphone everyone is talking about" on its official pre-order page.
