Hello, so I have this phone since mid October and I used only wi fi till now. I have 200mb mobile network for month but I really dont know how to work with it. First of all how to turn it on or it turns on himself when there is no wi-fi? When I turn my wi fi off it seams that mobile network turns on and in notification bar it does not show 3g but E with two arrows up and down, what kind of network connection is that? How to turn 3g on? Is there widget or sometging to turn on/off 3G?
