Quick Look: APNdroid
APNdroid is simply an on/off switch for your APN service. What this means is that while you are not using your edge/3g you can have it turned off, saving your phone’s battery. With your APN turned off you can still receive and make phone calls, and text messages like normal. But you will need to turn it back on if you wish to use the browser, maps, or want to send any MMS messages.
APNdroid is alsoÂ open source, check it out if you’d like to see exactly how it works. If you have ever been disappointed with your android device’s battery life, then please try APNdroid and simply turn off your wireless data while you are not using it. You’ll be amazed by how much longer you make it between charges, even if you just leave it off while you are asleep.
