Yesterday evening I went to use my phone after it had not been in use and it was very warm on the back. The only way I could get it to cool down is turn off my 3G. For some reason when I have my 3G on and I am not using the phone its using 3G for some reason. I also noticed it was draining my battery. When I turn 3G off it doesnt get warm or drain my battery.
What would be causing my phone to do this?
