Thus far, neither AT&T or Nokia have commented on the availability date of the Lumia 900 in the US, but rumors have stated that the phone was initially going to launch on March 18th, but it was delayed until the 22nd. Now, a new rumor has surfaced suggesting that the phone will be available to order online on April 8th (Easter), and will hit store shelves on the 9th. WPCentral spotted a comment on The Verge from someone who claims to be an assistant manager at an AT&T store in California who is stating that they are “gearing up” for the Lumia launch, and “its tentative for April 8”.
He also mentioned in his comment that AT&T will only initially be receiving black and cyan units, with the white one being sold if and when the device performs well. On top of this, a second commentor on the WPCentral post itself who also claimed to be from AT&T mentioned that he’s been told the phone is launching on the 8th as well. Now of course, this rumor, as with the others, should be taken with a grain of salt. I will attempt to ask around and see if I can get more information backing (or smashing) this rumor.
In a related note, WPCentral are hearing from a credible source that the finalized software for the AT&T Lumia 900 will be going out today, meaning that AT&T will have to reflash all of its devices.
