Monitor wifi usage?

Is there a way to have an alarm warn me every time I spent another 100MB and telling me the total I've spent on the last billing period to avoid going over my limit and into debt in Android?


It looks like NetCounter will do what you need


I'm using Network Monitor. With this free app you can track 2G/3G and WiFi traffic as separate stats. Also you can set up warning message for each stat.
