Know who loves it when other OEMs call him big poppa? Ballmer, that's who. So much so that he's opened up the company's coffers to Nokia and Samsung for a holiday blitz of Mango marketing. Hold onto your hats though, it's no carte blanche access to Redmond's Gringotts. According to a report on Mobile Magazine, inside sources claim MS has set aside ₤28 million (about $44 million) for the endeavor, with about ₤20 million of that reserved for Nokia's first Windows Phone 7.5 handset. This joint marketing effort is reportedly a broader extension of the cooperative agreements all parties agreed to, ensuring future WP devices get the media saturation they deserve. So, keep your eyes peeled this upcoming winter. We have a feeling you won't be able to escape the commercial onslaught, anyway.
