As rumored all week long Nokia has officially announced the beginning of the Windows Phone 7.8 update to its line up of Lumia handsets.

The update will be made available starting today and throughout February for the Nokia Lumia 510, 610, 710, 800 and 900.

This update brings several enhanced features according to Boc Ly’s post at the Nokia Conversations blog:

As well as major system updates, there has been a stream of exciting new features introduced to Nokia Lumia. These include Internet sharing, Bluetooth sharing, imaging enhancements like Camera Extras, and the release of apps such as Contact Share, Play To and Nokia City Lens that are available.

With Windows Phone 7.8 installed, your Nokia Lumia gets even better.

The Start screen experience is completely refreshed with the ability to re-size your tiles: small, medium and large.

In addition, there are also new options available on your lock screen, such as having a daily background image from Bing; plus there’s improved pocket and child lock screen security.

Plus, there is increased language support, meaning even more people get to enjoy Nokia Lumia.

I asked the question the other day is this Windows Phone 7.8 Update Too Little Too Late and that is still to be seen but I do know folks who have those second generation Windows Phone handsets have been anticipating this update for several months.

Now let’s see how this is received by those folks who have been waiting.
