Use a small tool to pry the digitizer and screen (together) from the frame of the phone.
This may take some time and careful work because it is glued down to the frame.
Be careful when you pull the lower part of this piece away from the phone frame because there is a ribbon attached to the digitizer that you don't want to break. There is also a ribbon on the side of the screen to be aware of.
