I want to change 3G dns setting on Android 2.1 device. I managed to install busybox on my device, i can also get dns information by using adb shell getprop | grep dns. The only problem is that it shows me net.pdp0.dns1 and net.pdp0.dns2, not net.rmnet0.dns1 and net.rmnet0.dns1 so i can't change the setting.
I know that net.rmnet0.dns1 is for 3G connection, so what about net.pdp0.dns1? How can i change to net.rmnet0.dns1?
Thanks
