After a long wait, Microsoft’s Windows Phone 7.8 update is finally hitting Nokia Lumia devices everywhere. The new upgrade delivers some tweaks and UI improvements to Nokia’s Lumia line (which includes the Lumia 610, 710, 800 and 900) which includes customizable homescreens and lockscreens as well as MarketPlace improvements. Nokia hasn’t really specified who gets the update first, although we did confirm with local reps that there are already people in the Philippines who are enjoying Windows Phone 7.8 on local Lumia devices. If you didn’t get a prompt for your update yet, don’t fret – the update is being done in batches and will continue till February.
