What is the correct length of flex (ribbon) cable for the Digitizer cable and the LCD cable? I've threaded the cables correctly through the mid frame, however, I keep encountering the same issue. Once I've tried seating the cables into the sockets, the Digitizer cable is too short by approximately 5mm. I've tried several different makes of the front panel display (front screen replacement) but have encountered the same problem with each and the supplier, stating each have been 'defective units'. It just feels a stretch to believe I've been unlucky in purchasing 4 that have all been defective. I can't check these against the original (Apple) screen, as it was too damaged and the removal process of these iPhone 4 screens is a nightmare. Any help is appreciated
