And why you need it so urgently?
Even a "big" step and update time from 3.90 to 5.92, and not too much changes. Almost all our feedback and suggestions go directly to trash 
(yes, maybe a new update can solve WiFi, but because it's a single, big fail, and previously working).
I don't even try now to test, suggest or feedback. Just wondering what my next "top-dumb" phone will be. Other one, i.e. smartphone - clearly, Nokia, not. Even being a big fan from years and years ago. No more.
Regards.
Once a phone is released, its just almost final with its Software. New updates are more importantly pushed to bring in stability and not lots of new features. Sure we'll welcome anything new being added with the update.
For now I only hope it brings more stability and solution to some common problems such as WiFi. Armagon said an good improvement to WiFi will be made available in the next update. Lets wait a little more and hope the update will be worth the wait
About the feedback, where was the feedback left? I'm sure noone contacted Nokia through proper channels to leave their feedback. These forums are just for User to User discussions with not much involvement from Nokia Support. However I do hope Nokia starts collecting feedback through these forums. A good implementation will be to give Top Contributors the power to flag an important or worthy post to be looked in by someone from Nokia. These are just my views though
@armagon :
not demanding to say the exact time and date of release, but we are saying that we have few problems regarding the present version so release an update ASAP(A little lower end phones also has got brightness option,as u mentioned earlier) !
AND ambient light sensor ....... i couldn't identify whether it works or not !!!!!!!!
Rather than that sensor, BRIGHTNESS ADJUSTING OPTION is much much BETTER ! (can reduce intensity at nights).
