AT&T has confirmed that Nokia's LTE-capable Lumia 900 will be available on April 8th for $99.99, an extremely aggressive launch price for a device billed as a flagship in AT&T's line — and arguably, a flagship for Windows Phone as a whole. The date lines up with rumors late last week and puts to rest some earlier fears that the launch may be pushed out to the latter half of the month. Pre-orders kick off online and in stores this Friday, March 30th, and both colors announced back at CES — black and a variation on the bright cyan first made famous by the N9 — will be available at launch. White, meanwhile, follows on April 22nd.
