The last official word we heard from Microsoft came on Nov. 28 when it claimed it was working hard to roll out the update, but it wouldn't be until the first few months of next year.
"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.
