Some lucky owners of Lumia 800 and 510 received the last official update for Windows Phone in advance of the 2013 release schedule and hopes for an early release ran high. Nokia squashed these expectations explaining that what happened was merely a “test run” targeted at owners of pre-production devices, who received a test version of the final update. The release schedule for Windows Phone 7.8 remains on track for early 2013. If you are not the patient kind, perhaps you could acquire said update through some other means, but you risk bricking your device and ban from Nokia’s official update service. So you’re better off waiting for now.
