Microsoft, Nokia and carrier partners are planning a $100 million marketing push for the Nokia Ace (also known as the Lumia 900) when it launches in the United States. While the Ace isn’t yet official, it has been rumored that AT&T will unveil the device during the Consumer Electronics Show in Las Vegas next week. We exclusively reported in November that the Ace will offer a 1.4GHz processor, a 4.3-inch ClearBlack display and an 8-megapixel camera. Other reports have suggested it will run Windows Phone 7.5 (Mango) and support AT&T’s 4G LTE network. According to BetaNews, the Ace will hit AT&T store shelves in March where it will receive “hero” status. It is unclear how Microsoft, AT&T and Nokia will split the $100 million in marketing, but the hero status suggests it will be the focus of AT&T commercials, print ads, digital ads and in-store marketing.
