The thing is, 4.6.0.185 and 4.6.0.190 are the same version of OS; 4.6. Whatever RIM did between build .185 and .190 screwed up Live Search. I think RIM needs to look into it. Live Search is compatible with 4.6, and that is why they haven't updated it. RIM dropped the ball here and did something to their software that denys Live Search.
