I recently purchased a HTC and it is well featured phone that I had ever used. HTC has many advanced features but it generally affected by scratches which really look too bad. I want HTC surround skin cover to offer protection from further damage.
On your home screen, make sure there is space for a widget. press down on the screen until the "add to home" screen appears. Click on the widget icon and scroll down to the settings icon and press the icon. Now click on the 'Mobile Network' icon and it will appear on your home screen !
Just tap the icon to turn on / off the mobile data..
