I started writing the new app, I suggest not asking for ETA as I have no idea myself when it will be finished.
As soon as possible as usual, but eh it takes time.
BTW I tweeted about it but: the real fix will only be available on ICS, as Samsung changed a few code lines in their driver that allows me to hack it live without kernel flashing.
Mine has a green tint as well. It is most noticeable on grey areas, such as the key board.
I've been using Screen Adjuster from the market to balance it out by adding more blue and red. After a few days of using it, go back and switch it off and you'll really see just how green the screen is, it is shocking.
The only catch with using screen adjuster to balance the colours is you lose some of that really nice deep dark black that the screen has.
With screen adjuster off, you can barely see where the bezel ends and the screen begins because the blacks are so dark... but you get the green tint.
With screen adjuster on, the blacks aren't as dark and you can see the difference between the bezel and the status bar for example, but the colours look more realistic.
So it's a compromise either way. But personally, I can't go back to the green tint after a few days without it, so the slightly reduced blacks are worth it.
