Sadly there has been no development at all on the AT&T model G4. No RUU's or anything. Which is why the AT&T G4 is my first Android phone I have not Rooted. Even the 815 European model has had very limited development.
Re: Will you be rooting?
I will once they come up with a Bootloader unlock for the H810. Right now the device is just too new and Development for it is going to be slow coming.
I keep my WiFi on because I work at home, but if I am going to be out and about I turn it off. Also if your using the power saving mode the WiFi is shut down when I am not using my device.
