there are a couple of option you can try. I have used them a little bit but it might contain the info you seek.
1) dial *#*#4636#*#*, brings up an option menu
2) dial ##PROGRAM, code is 000000, also brings up an option menu, this one can be used to change your phones vocode, but tons of other options as well
*****BUT BE VERY CAREFUL WHILE IN THESE MENU'S, CHANGES COULD BRICK YOUR PHONE*********
thanks for the info was not exactly what i was looking for though :P. unless i missed some thing in there, on blackberry if you go to dialer and hit menu you can view status if i recall that shows last call time and timer of all calls made.
