Windows mobile software - diary

I've currently got Agendus on my Sony Ericson, which has a week view on the diary in which you can make actual entries (ie not a block view). I'm looking to upgrad to a phone with Windows software, such as a Palm Treo or HTC 710. There is a version of Agendus for Windows (the Sony is Simbian) but I can't see from the blurb if it has the same week view. Does anyone know if it does? And if not, is there any phone that has such a view already (I know the P990i has but I can't get that any more). Your help would be much appreciated.
