Just to share...

I'm tired of mystery app that keep 'eating' my data. I've found an app https://market.android.com/details?id=net.ir.apptrafficfree that can show which application is consuming your data. Just to keep track.

Some app is a bit dodgy... there some data being transmitted even though it is not log in. Hmmm time to look back at the app permission.

Cheers
