Introduction

The front panel assembly, including the digitizer, ear speaker, and home button, can be replaced on the iPhone 3GS.

Video Overview

  1. 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. This will keep glass shards contained and provide structural integrity when prying and lifting the display.

    • Wear safety glasses to protect your eyes from any glass shaken free during the repair.

  2. Remove the two Phillips #00 screws from the dock-connector end of the iPhone.

    • Make sure to keep all the screws organized as you are taking the phone apart. They are different sizes.

  3. 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.

    • 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.

    • Be very careful when opening the iPhone so that the cables under the display are not severed.

    • There is a rubber gasket between the silver front bezel and black display assembly. A bit of force is required in this step to separate the iPhone's display assembly.

    • Use a small suction cup near the Home button to gently pull up the lower portion of the iPhone's display assembly.

    • If the display assembly is too damaged to allow the suction cup to adhere, tape with a strong adhesive such as duct tape may be used.

  4. The display assembly is still connected to the iPhone by several cables, so don't try to remove it entirely just yet.

    • The display assembly is still connected to the iPhone by several cables, so don't try to remove it entirely just yet.

    • Rotate the display assembly up until it is at an angle of approximately 45 degrees.

  5. 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."

    • 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.

  7. Rotate the display assembly up until it is roughly vertical. This will allow easier access for disconnecting the remaining cables.

    Edit

  8. Ribbon cable "3" is held in place by a FPC style connector. You must unlock this connector before sliding the ribbon cable out. The locking mechanism is on the opposite side of where the cable is inserted - it swivels upwards 90 degrees. Use a plastic spudger to lift the locking mechanism. The FPC locking latch is very delicate and is typically a different color than the body of the connector. (see the detail image of FPC connector open and closed)

    • It's impossible to properly reinsert a ribbon into an FPC connector unless the lock is disengaged. Make sure the locking latch is open when attaching/detaching the cable.

    • Keeping the tape from sticking to itself can be tricky. We recommend placing the tape on a wax-coated piece of paper (any sticker backing will do).

tf? what is the smart cart?

Tristan Haugh -

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.
