Windows Phone 7.8 is now available on Nokia's Lumia 800.
On Monday, Nokia confirmed that the Lumia 510, which is not yet confirmed for New Zealand, is shipping with Windows Phone 7.8.
"At present we have no more information we can give about wider availability of the update for phones running Windows Phone 7.5," Nokia said in a statement via email.
Windows Phone 7.8 was announced in June, and includes the new start screen Microsoft built for version 8 of its smartphone operating system. It allows users to change the size of the tiles used to access applications.
The update also doubles the number of theme and accent colours to 20 - so users can further personalise their phones - and adds new lock screen features, Microsoft said in a blog post last month.
Microsoft's blog post also provided some information on availability.
"We know you’re eager to get the Windows Phone 7.8 update, and we want you to know that we’re working closely with our hardware and carrier partners to get it tested, approved, and rolled out to as many devices as possible in early 2013," it said.
The long wait has left some users frustrated.
