George:
U need a "special" adhesive tape, a thin one, as the kind used for iphone 3GS touch screens.
Or you can buy another kind, it just have to be thin, STRONG and double sided!
What you do is: Cut the adhesive so it fits metal fram, NOT covering the sensors around the top.
After doing so, u fold the flex cables as they were on the old part. There should be some adhesive already on the LCD flex cables, that needs to be removed.
When thats done, you remove the coveredge on the doublesided adhesive tape, and place the touch + LCD firmly on it, now, press and hold for about 30seks, till you belive the touch is holding, mind the corners, press here also!
THEN your done, assemble the phone again, close your eyes and press the power button, hopefully your "lucky" and you got a picture on the screen hehe :D Good luck mate.
