Hello I am new to a whole Android and HTC experience as I have my lovely Legend only since 3 days I really love this phone, but there is a one thing which I am kind of worried about. Most of a time my phone is connected to a WiFi network at home, but when I put him on charge for a few hours (lets say over night) I find out that through that period of time my phone was connecting to a 3G network to download some data. That happens only when it's on charge. In a last two days I have lost 7MB of my usage because of that... Is that how it should be? Why my Legend is not using WiFi while charging??
