Find out size of all data ever downloaded Is somehow possible to find out size of all data I ever downloaded on my HTC phone?

edit:source from which I downloaded data will be also super

Thanks
Your carrier would keep track of how much you've downloaded over 3G.  I highly, highly doubt they do enough logging to tell you where all of it came from though (and if they did, they'd probably make you pay to access the logs if they let you at all).

There's no way to tell exactly what you've downloaded over WiFi, apart from browser history for file downloads if you've never cleared the list.  Presumably you could modify Android to log everything, but as far as I know it hasn't been done up till now.
