Just Simple Calendar Synchronization
CalCopy is a simple little iPhone app that let's you replicate calendars with the push of a button. Select your source calendar, your target calendar, and specify a time span -- CalCopy will make sure the target calendar has exactly the same events in the specified time frame as the source calendar. CalCopy will add those events from the source calendar which are missing in the target, and will remove those events from the target calendar which are missing in the source.
For example, CalCopy comes in handy if you have access to your company's business calendar from your (business) iPhone only and want to replicate it to another (private) calendar. Or if you want to make a copy of someone else's calendar. Or if you want to backup your calendars.... or or or... :-)
CalCopy is available via Apple's iPhone AppStore here:
