CSHARP123 writes "Ballmer 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. Samsung is also due to unveil a major Christmas ad push for the Omnia W with an estimated £8m spend. Maybe this is what Samsung gets for making a deal on patents to cover Android OS? Not a bad deal for Samsung."
