P1 claimed that the latest '650 CNG firmware would fix the power down timeout, but it still resets to 30 seconds globally after making a phone call. Why does this seem so hard to fix?

Is there something about setup I'm missing, or is there a utility or patch that actually fixes this? Tried a search, couldn't find.

FW = 1.51
SW = Treo650-1.17-CNG
