You know what? That's actually pretty useful and I hadn't really looked that closely at it. It does data by app and I can select the date range (although only to a maximum of a month). I had played with ICS on the HD2 but not much. Before that it was Gingerbread mainly. Not sure whether the data app was that useful or not in Gingerbread. Perhaps it was and I just didn't look hard enough... Ooops. Thanks for pointing me at it... This will probably do.
