The update, which brings some of the features present on the higher-powered Windows Phone 8 software, has become unofficially available through the Navifirm site.
Those who have already 'flashed' the device and upgraded to 7.8 are experiencing features like Live Tiles of varying sizes and the ability to make Google the default search engine within the IE app.
"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," the company said.
"As we work to quickly get this in the hands of our loyal users, we're also striving to deliver a high-quality release and ensure a smooth transition for our widely expanded services."
Windows Phone 7.8 was announced back in June in the hope of bridging the gap for existing handsets that were not eligible for an upgrade to Windows Phone 8.
