WM5 call monitoring software

[Guest Webreaper]

So, I'm going to get an XDA Mini S. Ideally, I'd like some software which can track my phone usage and predict my phone bill, so I can make sure I'm not spending too much. :-) I.e., you put in rules (number of free minutes, call costs for local, national, 0870, etc) and it keeps a running total of how much the bill would be.

I presume it's possible, but is any software out there?
