iPhone: monitor data (internet) usage

Question

is there a way to monitor how much data(internet) each application used?

if I cannot monitor applications is there a way to get all internet requests information? (get data passed, url, etc)

(I would like to use this info in an app Im developing for iphone)

Thanks

No, you only have access to your own application's sandbox, and therefore can only track the network usage of your own application.
