Is it possible to say put on just the digitizer such as this one or does it require some to much hard work? just can't an answer right now, so sorry if its a stupid question.
Just change it and it will work..
However, keep in mind the the digitizer is very well fixed in the front cover.. You probably have to glue the new one. The best thing you can do is buy the digitizer already mounted on a new front cover.
