iPhone 3G Disassembly Guide / Teardown Manual

Is there something worng with your lovely 3G iPhone? or is the LCD broken, or the battery can not be rechargeble? Do not worry about them. Just believe that you can do it yourself. Follow the our repair guide, you will find it is not so difficult. However, at the beginning you must prepare the opening tools, such screwdrivers, levers, picks.

	Step 1 — Battery Remove the two Phillips #00 screws from the dock-connector end of the iPhone.
	Step 2 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.
	Step 3 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.
	Step 4 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."
	Step 5 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."
	Step 6 Some iPhone 3Gs may have the connector colors reversed (black plastic tab, white connector). Make sure you're flipping up the tab properly, otherwise you may damage the connector. 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.
	Step 7 Insert your SIM eject tool or a paper clip into the hole next to the headphone jack. Press down on the tool until the SIM card tray pops out. Grasp the SIM card tray and slide it out of the iPhone.
	Step 8 Use a spudger to disconnect the ribbon cable labeled "4."
	Step 9 Use a spudger to disconnect the ribbon cable labeled "5."
	Step 10 Use a spudger to disconnect the ribbon cable labeled "6." If you have an iPhone 3GS, refer to picture 2 and use a spudger to disconnect the ribbon cable labeled "7."
	Step 11 Carefully peel up the small sticker labeled "Do not remove."
	Step 12 Remove the following 8 screws: 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.
	Step 13 Use a spudger to 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.
	Step 14 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.
	Step 15 Slide the logic board towards the dock connector and out of the iPhone.
	Step 16 Use a spudger to pry the battery up from the rear panel. The battery is attached with an adhesive strip around the perimeter of the battery. To prevent the battery from bending during the removal process, we recommend against using just the plastic pull-tab .
