Assume an iPhone is jailbroke, is there (private/public) API or database to access the recent phone call list? I'd like to delete an individual Recent call entry. Thanks!
Accessing iphone call log through code has been discussed many times.
The answers say that it is possible on a jail broken iphone. You need to access the data base:
/private/var/wireless/Library/CallHistory/call_history.db
But of course there aren't any public APIs for doing that. I'm not sure how your jail broken iphone is going to react to your playing with this DB. So i would suggest not deleting anything programmatically.
