For some time now, the tech world has been hotly debating as to when Nokia will launch its Windows Phone 8 Lumia devices. The Finnish mobile maker has indicated that it will unveil the Windows Phone 8 Lumia devices at its Nokia World event in September. These phones are expected to go on sale just in time for Christmas.

This means that September could turn out to be a decisive month for Nokia. The company has been depending heavily on the new mobile OS from Microsoft to regain lost ground and fight better against Apple and Samsung. And it is readying devices that are compatible with the new OS.

Nokia is so determined to seize the opportunity that Windows Phone 8 brings, that it is bringing together its employees from different departments and will send them to train and educate retail staff in US carrier stores.

The aim is that by providing a thorough insight into what Nokia’s Lumia range can do, the retail staff can provide a better service to potential customers. The group has already been nicknamed as the Nokia Army.

When Windows Phone 8 was officially unveiled, Nokia was forced to admit that all its current range of Lumia phones, including the flagship 900, would not be able to be fully updated to the new operating system.

Nokia World  is happening on September 5-6, which is one week before the iPhone 5 is expected to be unveiled.
