Amazon had the digitizer and screen combo for $15 from Centaurus Electronics. I've ordered it twice now and it is the full touch screen. My son is really clumsy (lol). Get an electronics screwdriver set for the tiny screws (usually T10 but I have seen some phones as small as T6 screws). The wires have "snaps" but do not pull them. Lift at the snap to remove.
I am actually looking for a parts diagram for this model if anyone knows of one existing. I need the top plastic frame for a proper repair. Otherwise the digitizer doesn't sit properly even in a protective case. Thanks
