Okay so i got the at&t sales representative to add a medianet package for me of 5 mb. I know that you could not use media net on a blackberry but i dont know how but it worked anyways. So i added Opera Mini. I only carefully go on the internet just so i dont go over my limit. I now use opera mini, can somebody tell me how much kilobytes opera mini uses per page or something like that.

Nobody can say for sure how many kilobytes any particular site or page will load. If you watch the progress bar at the bottom you'll see how many bytes are being loaded. Make sure the sites you visit are mobile sites as they are less data hungry, but even then I have seem anywhere from 7 - 70 kb's.

If your 8310 is still running on OS 4.3.x.x then you could try a little app called MiniMoni; it is a traffic monitoring program that monitors data usage. It's not 100% percent accurate on all networks, but is pretty good.
