    • 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.

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

  3. iPhone 3G Logic Board Replacement: step 3, image 1 of 1
    • 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 bottom 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, or thick, clear packing tape may be used.

    • 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.

    • Use a spudger to disconnect the black ribbon cable labeled "2."

  7. iPhone 3G Logic Board Replacement: step 7, image 1 of 1
    • Use a spudger to flip up the white plastic tab holding the remaining ribbon cable in place. The white tab will rotate up 90 degrees, releasing the ribbon cable.

    • Slide the black ribbon cable out of its connector, and remove the display assembly from the iPhone.

    • Insert your SIM eject tool or a paper clip into the hole next to the headphone jack.

    • Five 2.3 mm Phillips #00 screws with partial threads securing the logic board to the rear panel.

    • Two 2.3 mm Phillips #00 screws with full threads securing the logic board and camera.

    • One 2.9 mm Phillips #00 screw from beneath the "Do not remove" sticker.

    • Use a spudger to gently remove the camera retaining clip, (formerly secured by the removed screw) and gently pry the camera up and out of its housing in the rear panel. The camera cannot be removed entirely yet because it's connected to the bottom of the logic board.

  15. iPhone 3G Logic Board Replacement: step 15, image 1 of 1
    • Use a spudger to gently pry up the end of the logic board closest to the dock connector.

    • If the board won't lift up, double check to make sure all the screws securing the logic board have been removed.

  16. iPhone 3G Logic Board Replacement: step 16, image 1 of 1

Step 6: When I attempted to 'rotate the white connector 90 degrees' my white connector broke into 4 pieces... my phone is now beyond my repair. I feel soo dumb. I should have used a pair of eyebrow tweezers (two flat blades that press together) to wiggle the #3 ribbon cable in/out of the connector instead of trying to pivot it.

Anyone know how to repair this? Drop me a line at quathiaski(at)gmail.com

I have found out why I broke my connector all to heck... I attacked the wrong end with my plastic prodder. Work on the BLACK end... it moves...not the white end.

You are not dumb, you is learning.

Have a nice day :)
