Wow. Does anyone also else feel this info should be accessible in little more easy and simpler way :-\. Well, at least there is one way it is accessible.
go to the contacts list and open the contact for which u need to see the call duration. then tap the menu button and select histoty.it should show u all the call durations with date for that particular contact
This kind of sucks to not have call duration shown in call log. Is it hidden somewhere, or is it just not present by default??
