3G Watchdog v0.14.0 Application for Android | Tools
Although this is not essential, it may help someone. It is interesting to see what is occurring with your data.
0.14.0: Vibrate now optional. Motorola Droid support (beta).
Monitors your Mobile Internet (3G/Edge/GPRS) traffic usage, shows a status icon (green/orange/red) in the notif bar and/or a detailed report page. Useful if your "unlimited data" plan actually has some restrictions (read the fine prints!)
