The Windows Phone mobile operating system from Microsoft was just upgraded from its initial release to version 7.5, referred to as "Mango." While this update has been distributed to the majority of eligible users of Windows Phone-equipped smartphones, it has not reached those who own the Samsung Omnia 7, in addition to several other phones.

According to PCWorld, owners of Omnia 7 mobile devices in Germany, Spain, the Netherlands and the United Kingdom have not received the upgrade. Although difficulties with the upgrade process were publicly announced at the beginning of October, Mango was promised to some of the affected users by the end of that month. It has now been pushed back to the first few weeks of November.

The news source reports that even after the distribution process formally begins, users will receive the Mango upgrade, its software and smartphone accessories in a staggered process, rather than all users receiving at once. Additionally, Omnia 7 owners in Spain have no established date upon which to expect their upgrade, and the country's wireless provider refused to comment on the matter.
