If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping the glass.
-
Lay overlapping strips of clear packing tape over the iPhone's display until the whole face is covered.
-
-
-
Remove the two Phillips #00 screws from the dock-connector end of the iPhone.

Remove the metal handle from the suction cup. It's easier and safer to grip the suction cup's base instead of the metal handle.
-
Use a small suction cup near the Home button to gently pull up the lower portion of the iPhone's display assembly.
-
-
-
Rotate the display assembly up until it is at an angle of approximately 45 degrees.

Continue to hold the display assembly with one hand, and use your other hand and a spudger to disconnect the black ribbon cable labeled "1."
-
Ribbon cable "1" is connected with a plug style connector. The block at the end of the cable is the plug which is simply pushed into a socket on the circuit board. No other locking mechanism is used.
-
-
-
-
Rotate the display assembly up until it is roughly vertical. This will allow easier access for disconnecting the remaining cables.
-
Use a spudger to disconnect the black ribbon cable labeled "2."
-
-
-
Slide the ribbon cable out of the connector, and remove the display assembly from the iPhone.
-
-
-
Remove the single Phillips #00 screw from the corner of the display assembly.
-
-
-
Remove the two Phillips #00 screws from the right side of the display assembly.
-
-
-
Turn the display around, and if there is a thin strip of black tape on the edge of the display assembly, carefully peel it up.
-
-
-
Remove the three Phillips #00 screws from the left side of the display assembly.
-
-
-
Turn the display assembly over and again carefully insert a metal spudger between the two metal rails along the edge of the display assembly. Gently rotate the spudger to lift the LCD up from the glass.
-
-
-
Separate the LCD and glass by sliding the LCD panel away from the ribbon cables on the glass.
-

do not forget to remove the smart cart!!
if less than an hour to remove and replace the new front panel.
tf? what is the smart cart?
The hardest parts are separating the glass from the plastics and then re-attaching it. It would do you well to buy the 'custom' double sided sticky tape they sell here at ifixit. I used regular double sided tape and it took a long time to cut and fit properly so all sensors would remain working and the screen would be held in place.
If your screen is severely damaged, there is no way to separate the digitizer from the outside glass without destroying the digitizer, is there? I couldn't do it. Also, nail polish remover is good for getting rid of the adhesive!
Be careful putting the new screen back in. I got almost all the way to done and everything was working perfectly - then I had trouble getting the bottom portion of the assembly (near the home button) back in.
I forced it a bit thinking I had squeeze it in and cracked the new screen. Doh.
