Microsoft will have to quickly communicate officially to the compatibility of Windows Phone current (7.5.x) with the next Windows Phone 8. Indeed, the rumor continues to grow, fueled by more or less official statements and perfectly contradictory throw trouble on the strategy of the Redmond company.

Since the launch of Windows Phone, the publisher has highlighted the homogeneity of experience with terminals updated in a comprehensive and automatic. Objective, avoid fragmentation of the park to Android.

But since the announcement of the significant upgrade to its mobile OS, nothing works.
