I am using Nokia N900 with postpaid plan of DU (service provider of U.A.E.). The postpaid plan offers FREE 100 MB data usage and with this provider usage of 0.facebook.com access is absolutely free.

Strangely 0.facebook.com usage starts consuming data bandwith in several MBs, even though you do not click on external links and/or download images that apply standard data charges.

With default browser of Nokia N900 is maximum and if I use Opera browser, the problem still continues, but the incorrect data usage is restricted to less MB.

I use Data Plan Monitor tool to monitor my data usage and clear it on the day of my DU postpaid bill generation so that a TOTAL usage could be monitored in order to identify correct time to TOTALLY STOP USING INTERNET thereby avoiding extra payments

I am wondering if there is any tool for this handset that captures/logs complete details like

URL/Application ... Date/Time Stamp .... Total Data Usage in MB

like this columnar information could help us to identify any background service or port of this handset that is directly responsible for such an annoying bug.

Hope in this forum someone responds to this thread with possible solution or MAEMO developers bugfix this in near future.

But anyways... it's one handset I would still continue to use for years, as it quite impressive otherwise.

It's because MicroB(the default browser) faithfully follows the HTTP standard. Opera does too, but it uses special compression to reduce the data usage.

What am I talking about?
Apparently, Facebook has a... problem. Whoever designed/works on the site majorly screwed things up; The headers of *all* files tell the browser to re-download it every couple of minutes, expecting changes. This results in ridiculous amounts of data usage(and wasted power), even when it doesn't seem to be doing anything.
A properly configured site would have static content -- Like images - cached for several days at least, and dynamic content -- the small amount of HTML data -- reloaded fairly frequently.

At least, that's what I heard on Slashdot. I *refuse* to even touch the site with a 10-foot poll myself, so I can't really check myself.

you can try the htop or even conky app, but i'm not sure if they will be detailed enough for you.
