At last, I discovered but after 2.5 years! :-(
Today, after 2.5 years of using my dear Cell, the Nokia 6260 - clampshell shaped 'brick' :-), I discovered a super good feature (pretty common requirement though) that can save me good amount of money on every call! :-) As the saying goes, 'Need is the mother of all inventions', in my case I had the need to see the 'real-time' call duration ie. when the call is in progress, I wanted to see how much time has elapsed. This was and is required coz countless times, indeed, countless times it has happened that I end a call at the every beginning of next minute (1 call rate is calculated for every 60 seconds), means I end a call at 01 second or 02 seconds or 10seconds or 15seconds. After every call, I curse myself was having wasted some money for just this much time where I could have spoken a bit more till 55 or 58 or 59 seconds!! I dont know how much my money has gone to Bharti's kitty just because of this and I hate to the core! :-(( So, I searched on the net...
