Need some iphone 3gs battery replacement instructions?

Battery replacement in iPhone 3GS is very tricky. I will give you a step by step procedure, just folow the instructions very carefully. Read the whole procedure once before you start doing it step by step.

1. Remove the SIM tray using a pin or paper clip.

2. Locate two screws on the bottom the phone. Unscrew them and slowly detach the screen using a prying tool. Be very careful as the screen is still attached by 3 ribbons. Just open it up but dont pull it off.

3. Beneath the screen locate three ribbons numbered '1' , '2' , '3'. These are the ribbons holding the screen to the motherboard. Remove them with a screw driver in the same order of their numbering.

4. The screen is now detached and you can proceed by locating the other ribbons numbered '4' , '5' , '6' , '7', and the screws below them.

5.Remove the ribbons and unscrew them all in the order of their number and remove the warranty sticker that you will find under the ribbon '7' and unscrew it too.

6. Now you can lift the motherboard away and you will find the battery. You can pull it out as it is only attached to the back with a tape and nothing else.

7. Replace the battery with the new one and put back all the parts together going from step '6' to step '1'.
