Not sure if it's been mentioned but there is now a update for Handcent live to fix the Evo 2.3.3 bug. Unknown if it actually fixes it.
I installed it, and while it works, all of the options have been removed unfortunately... You get a green blinking light and that's it (you also can't change this for individuals either). I am not particularly happy about that given that wimax notifier also doesn't work... There is still no way to differentiate a text from another alert at this point.
Now that I think of it, what we are left with is exactly as the system does anyway. I haven't rebooted since I did the install though. Maybe it will change?
