This is for jailbroken iPhone.
Is there a way I can access the call_history.db on iPhone which is a database where apple logs the phone call information.
It
it is located in /private/var/wireless/Library/CallHistory
if you ssh into the phone through terminal, and you enter
find | grep "name of file you are looking for(case sensitive)"
It'll normally pull it up for you.
In iOS 11-13, it is located at /var/mobile/Library/CallHistoryDB
/var/mobile/Library/CallHistoryDB
