gprs counter for mobile - WM5

Tried out the built-in gprs data counter in HomeScreen PlusPlus, the settings for which which can be accessed via Start -> Settings -> Personal -> Today -> Items -> HomeScreen PlusPlus and clicking the Options button. Or by pressing and holding near the cpu icon.



But for some reason it did not work on my phone. Maybe I should have tried rebooting the phone after setting it or something. But anyway, it showed 0 incoming 0 outgoing even after using nearly an MB - Rs 5.40 worth - by just seeing half a page of slashdot in skyfire!
