188.8.131.52 is now officially out for the 9530 and can be downloaded via desktop manager once plugged in to your computer...
It's the "legit" version for those who couldn't find the leaked one, but so far, still experiencing the same functionality as the leaked version (which I had no doubt anticipated).
It still managed to update the core files v.4.7 thru desktop manager, even with the previous upgrade so maybe it did something, if so, I haven't noticed yet, but it's only been a couple of hours...
report back if anyone notices anything!
(You can also check here
for upgrades, but when I tried it didn't work)
best of luck!
