iPhone Cal,Tasks, Contacts Application?

[fullmetaljacket]

Hi guys! Anyone who knows what iPhone application should I get to get slightly the same functions as Agenda Fusion for Pocket PC or Windows Mobile 6? This application is great in organizing your appointments in combination withyour tasks and contacts. This app is one of the reasons why I still hold on to my HTC Touchpro inspite of having an iPhone. I found "Keytasks" but still not the same. You might have information on any application similar to this...

As of this time there isnt a PIM app available for the iPhone in the App Store. i guess Apple has restrictions for PIM Apps
