just to start i got the smallest data pack available, and cause you had to get a data pack. i was just wondering how much each thing takes up of your data pack, like im scared to even attempt blackberry messenger in fear of going over my data pack usage.
i only started with 15 $

I guess since each data app uses as much data as you use. If you don't browse the web too much, it won't use too much..

I think MiniMoni works as a data-traffic counter.

I use MiniMoni and you can set the billing period of your data plan to the day. Mine is monthly and I have set it to zero my counter at midnight on the last day of the month.

One other thing, disable the graph update. I had the feeling that it slowed down my phone just a bit when it was running.

MiniMoni is also free.
