Mogul backlight randomly turns on while device locked

[Alives]

I think this has to do with the cell signal. I locked mine on EVDO and the backlight didnt turn on randomly at all for over an hour, but then I couldnt get calls because sprint doesnt do voice over evdo yet. I havent tried locking it to 1x only. I also notice every time it does this the signal level is low or is on 1x instead of EVDO. I also have confirmed that MANY other people have this issue as well.

I cant find a fix for it yet. I assume its some sort of notification that your cell signal changed or something like that. Anyone have any ideas?
