[Touch Diamond, MDA Compact IV Themes and Apps] r00sick:
So, I found tweak:

"HKLM\System\CurrentControlSet\Control\State\ScreenOff\acs1:" change to "1"("0")

"HKLM\System\CurrentControlSet\Control\State\IDLE\acs1:" change to "1"("0")

But G-Sensor still isn't works with InCallTweak...

Then I look to log:

Here I see, that TLP can't fix second Landscape position of device. Whether I too quickly move, whether TLP too long thinks (about 1000ms, when switching on screen). So if I change gesture to "1-5-6" and set CmdOrientationTime not less than 2500 - it works!

Maybe it will be useful for other Omnia owners
