If for some reason you need to know the numbers a Windows Mobile Smartphone (2002 or later) or Pocket PC Phone (2003 or later) has been calling, you'll like this simple (and free!) utility called CallHistoryExport.

The small app saves all call records into a file called "callhistory.tsv," which you can open in Excel. Finally, here's a way to see if you're significant other is ringing up that secret love. Just get his/her's gadget, install the program, and copy the call log every chance you get. Mwahahaha.

Thanks to CoolSmartPhone for the heads-up.
