Thanks to our member Vidi who informed us. It was released yesterday so it's rather old news but a carrier known as BASE, has released an official OS for the 8520 Device. 188.8.131.526 is now the latest known official OS for this device. I have installed this OS onto my 8520 but I really don't see any difference between this one and .286. Either way, if you wish to download 184.108.40.2066 you can do so by clicking here.
