How To Shutdown 3G Connectivity On the Android Phone

The T Mobile G1 is a great phone. Among others, it can seamlessly connect to the web and sync data. The problem with this, however, is that 3G connection is always on and when you have a prepaid data plan or load, it gets eaten up quickly. This is why I could not use my G1 full time until I discovered this wonderful app on the Android Market: APNdroid. What it does is simply to turn on or turn off 3G connectivity. With 3G off, you can still make and receive calls and create and receive text messages. Basic uses for the phone, right?
