A. Yes, it's actually quite easy to see the GPRS data use for each session online, but you do have to get your head around the way Nokia think. Firstly, Nokia really don't want people's log files growing and growing (remember that voice calls and SMS use is also logged), so they put in a time limit with a very small default value, '1 day'. Outside of the last 24 hours, there's simply nothing available and it's easy to assume that no individual call or session has been recorded.
In addition, the peculiar design of the Log application means that you need to press the navigator right on the opening screen, to get to the log 'proper'. If you select 'Packet data' instead (as seems logical), you simply see the overall summary that you've already found. But once you tab right on the front screen to find the main log, you'll see all voice and GPRS sessions from the last 24 hours and selecting any of these brings up a dialog with the detailed information that you need.
If you need to increase this 24 hour limit, use 'Options | Settings' and change 'Log duration' to either '10 days' or '30 days'.
