I’d rate it the hardest repair in earth!
These screws are M1.4.
Screw is M2 x 5mm long.
No need toremove this. The cable squeezes out of the gap under the case with enough length for the antenna plate to be out of the way.

Reassembly:
Replacement double sided adhesive strips are applied to the case first. Figure which strips go top, bottom and sides. Start with the top or bottom corner. Apply the side strips last so you can figure which side is which.
Make sure the front camera and its window are clean. Use a strong magnifying glass and air duster. You won’t be able to get any dirt out unless you have more adhesive strips to use.
When you are ready to assemble, peel the backing off the double sided adhesive.
Support the screen at 90deg to case. Reattach cable connectors. Attach new battery connector then carefully position new battery with exposed adhesive into position in the case.
Attach connector clamp plate with 4 screws.
Carefully position the screen in case starting from the bottom edge. When it fits all the way around, press firmly round the edges to seal.

Cleaningoff the old adhesive:
Remove the old adhesive from underside of the glass and the edges of the case. This was the most time consuming part. Took 2-3 hours, because the original adhesive was really gummy and i didn’t want to damage any parts with harsh solvents. (I used a series of methods": citrus oil adhesive remover, methylated spirits, sticky tape stick and lift off.)
Making sure the edges of the glass and case are spotless ensures a good result when applying the new adhesive strips. New strips can be gently applied, peeled back and reapplied to make 100% sure they are in the right place. If adhesive residue is still present the new strips could get stuck in the wrong place and be impossible to reposition.
The vibrator motors die with use, so it could be that they just died coincidentally. I have replaced two on two phones. There are two models of vibrate motor - one with bent metal contacts and one with two coil springs. There were two different vibrate motors in the two iPhone 3G 16GB we bought at the same time. I chose to buy the motors with the coil springs, since they should maintain contact better over time.
Note the photograph shows the two tabs on the vibrate motor visible - this is incorrect. The tabs go into slots in the rear case. The vibrate motors behave better attached to the rear case with a small dab of neutral cure silicone, which eliminates a nasty rattly vibrate noise.
I note a lot of people forgot to retrieve the chromed trims from their old case. I tried to edit to ensure someone next doesn't make the same mistake, but my edits got rejected.
[* black] The rear panel, attached front bezel, camera housing, chrome trims, microphone/speaker grills, and volume switch remain.
[* black] Use a spudger to remove the camera housing and its chrome trim ring. When reassembling, note the chrome trim ring is keyed to the camera housing.
[* black] Use a spudger to remove the microphone and speaker grilles from either side of the dock connector. They are attached with adhesive.
[* black] Use a spudger to remove the headphone socket chrome trim with plastic surround (stuck with the blue glue on the photo).
[* black] Carefully pry the glue join between the metal bezel and the plastic case. Remove the bezel and the volume switch. The volume switch has attached plastic spacers between it and the volume switch mechanism which must be retained or replaced for the buttons to protrude enough to be pressed. When gluing the bezel to the new rear case, do not apply glue to the part of the bezel which retains the volume switch.
[* black] Remove the grey sticker from the middle of the case.
[* black] Refit the removed parts using their attached double sided tape or a suiitable flexible glue (eg polyurethane adhesive).
[* black] Refit the removed parts using their attached double sided tape or a suitable strong and flexible glue (eg polyurethane adhesive).
Replacing the motor, I have just done two phones. One makes a rattly vibrate noise, which I think a bit reminscent to my iPhone 3G when new. The second I used a small dollop of neutral cure silicone between the case and motor (staying away from the rotating mass). The annoying vibration noise is not present on the phone with the silicone, so I will redo the first.
Interestingly, the two phones had different motors. Both iPhone 3G 16GB - one black and one white bought at the same time. One had the motor with coil spring contacts, the other had the bent metal contacts. I decided to replace with the coil spring contacts having read a possible issue with vibration affecting the bent metal contact.
I had more joy using a home-made spudger from a bamboo skewer. Being thinner, it can release the connectors from the end rather than a side or corner. (I also tried all the different spudgers made by Menda Tools.)
