Bandwidth Usage Monitoring

[cmajewsk]

Does anyone have an app where you can see what application is pulling data? I only get 1G a month and for what I do on my phone: ActiveSync, Twitter, RSS Hub (no auto update), occasional web browsing, Google Maps, weather - that's all that pulls data as far as I can tell, it's more than enough.
Just the other night, I went from using 315MB for the entire month of December to now over 800MB. I then kept hitting the commend telling me what my data allotment was at every few minutes, and it was going up by a meg every two minutes or so. I turned off everything that was automatic, ActiveSync, weather, twitter, and it was still climbing but just not as fast. Finally I turned off the Data Connection, and that ended it.
So now I have a lowly 180MB for the rest of this month. Any suggestions?
