After seeing leaked photos and rumored specs for the Nokia Lumia 900, I’m sure many of you are excited to know more about this device. According to betanews, the marketing campaign for the Lumia 900, which is also known as the Nokia Ace, will run about $100 million. Their source also claims that Microsoft has reached an agreement with the AT&T to give it “hero” status.

Update: winsupersite claims it is actually closer to $200 million.

The Nokia Lumia 900 is rumored to ship on AT&T on March 18th, 2012. Features for the Lumia 900 include Windows Phone OS, 4.3-inch WVGA display, 512MB of RAM, 8-megapixel camera, and 1830mAh battery.

According to betanews, AT&T itself will promote the Nokia Lumia 900 in its advertising, through its retail channels and direct store associates to push the device within its stores. You probably know another “hero” phone from AT&T. Hint: iPhone.

I’m curious how the $100-$200 million will be spent here in the US. The marketing campaigns for the Nokia Lumia 800 around the world have been amazing so far.
