How do you know weather you are using WiFi or data?
should say on ur screen..data would pull up 1x,3G, or 4G.. and wifi on my HTC is a small dot with 3 lines over it in a form of a rainbow
Close your data and connect wifi
On my iPad it shows a couple of rows of semi circles with a dot. Depending on the number if semis and the dot I know how much wifi I have. The data by Verizon shows up with the name Verizon and bars
