Hi, there an app that monitors data usage?
I use an app called CALL METER NG (Free).
Call Meter NG - Android app on AppBrain
i use network monitor which is also free on the market
3G watchdog is another excellent alternative to the ones already mentioned.
THAnks got one called phone usage
There's also TrafficInfo and TrafficStats, which each can track data usage on a per-app basis, but both require Android 2.2 "Froyo".
Separate names with a comma.
