Nokia announced that the Nokia Lumia 900 will be released sometime in May, but gave no exact date.
Well, according to industry sources (Phones4u UK) of WPSuperFanBoy, the Nokia Lumia 900 will be available on May 21st for UK residents, that gives At&t the 45 day exclusive for the Lumia900.
This is news from unconfirmed sources, so you can take it with a pinch of salt.
In unrelated news, the international version of the Lumia 900 is now available for pre-order, well I wouldn't necessarily call it pre-order, more like reservations,
NStore.it is taking reservations for the Lumia 900, though they gave no indication on when exactly they intend to get the device
