We’re all waiting for Nokia to unveil its first smartphones running Windows Phone Mango. Though Microsoft’s platform is not as popular as those of Android and iOS, many analysts believe WP will still show itself. Probably, Nokia thought this way when signing a cooperation agreement. These companies, plus Samsung, are very serious and the first steps are already taken.

According to a source close to Mobile Today, Microsoft will spend £20 million to promote Nokia’s smartphones powered with WP Mango in the UK. That’s definitely not a shocking amount, but it shows Microsoft’s plans in promoting its native mobile operating system.

Microsoft’s also cooperating with Samsung. The first handset running Omnia W is already available for purchase. However, it’s not out of attention and Microsoft’s planning to spend £8 million for a marketing campaign.

The amounts I mentioned don’t make up the whole budget the three companies are going to spend on marketing campaigns for their smartphones, as each of them will promote a certain feature. Well, Nokia will promote Windows Phone Mango’s social networking features, apps and games, while Microsoft’s money will go to the “in-store marketing.” I guess something similar will happen with the Omnia W.

In my humble opinion, once the Nokia Windows Phone smartphones are launched, the budget will increase.
