Default Data logging / tracking app

Im getting some very expensive data bills coming in from when I am roaming. I get a popup whenever my email trys to connect asking if i want to connect and incur roaming charges. I deny this and use webmail from my laptop. I do not use the internet or anything else. Yet Ive still used 4MB in 24 hours while in Germany a couple of weeks ago!

Is there an app that can tell me what is connecting, when and how much data it has transferred?

Ie..

Weatherpanel - 29/06/08 @ 14:10 - 130kb
Outlook - 02/07/08 @ 07:00 - 30kb

Does Phonealarm or SPB monitor go this indepth?
