what i need to do is write to a log how much data did user downloaded and sent. every 24h data will be send to a server, the log ill be erase, and new data will be written.

as i understand-so.. if BB is almost always connected, probably that is the reason why getNumberOfPacketsReceived()/Sent() always return something. but i need an information of the data sent/received when user knows it (par example when he opens a browser and download something). i need to get somehow info about user's internet activity for which he would be charged!

also-getNumberOfPacketsReceived()/Sent() returns data in bytes?
