With the new API to access native iCal database entries in iOS4, calendaring applications are now able to CRUD (Create, Read, Update, Delete) native calendar database entries. Prior to iOS4 calendar apps maintained their own database and relied upon other syncing technologies (ie. Google Cal) to share data. I know that Pocket Informant is working on version 1.60 which will fully integrate the calendar database. I would like to keep a list of PIM apps that use the native iCal database. So far I have only been able to find 1: 1. Week Calendar (1.99) - Calendar that displays in Week format. If you know of any apps that interface directly with the iCal database, please feel free to add them. Thanks.
