You mean they are doing a per-application blocking of mobile data on non-rooted devices?
No, I'm talking about blocking all 3G/EDGE/GPRS internet, when it reached a certain number of megabytes on non-rooted devices and reconnecting it the next day (or another period of time).
Just look at 3G Watchdog Pro by Richard Gruet, for example.
And it would be nice to have ability to count 3G/Edge/Gprs or Wifi traffic per-application. I'd like to know what the hell my 3G internet leaks so quickly.
