AT&T has some teaser on its home page stating that some exciting thing joining their line-up. I’m not sure its for Lumia 900, it may be for Apple iPad LTE device that will be announced later today. If its for Lumia 900, well & good. As per our previous reports, Lumia 900 & HTC Titan II should launch for AT&T on March-18th, so these teasers might be a right time for it. But still there is no official word on the product launch from Microsoft, Nokia & AT&T. Lets see what happens!
