iPhone 3G
Second generation of iPhone. Model A1241 / 8 or 16 GB capacity / black or white plastic back. Repair is more straightforward than the first iPhone, and requires simple screwdrivers and prying tools.
Repairing iPhone 3G Home Button
User-Contributed Guide
An awesome member of our community made this guide. It is not managed by iFixit staff.
That pesky home button is connected to the assembly by small, and fragile cables. If it is even slightly gripped the wrong way during the repair of the phone, it can be broken. I had this problem myself, and decided to make this guide for others.

I did not take any of these images. I took these images from various iFixIt Staff guides, as well as google images. Thanks to all of you for reading, hope this helps! Feel free to leave any comments, good or bad, to help me improve the guide for others.

-
Attach the small suction cup to the iPhone, above the home-button.
-
Grip the suction cup, and start lifting the display slowly, and gently, making sure not to remove the display completely. There are still ribbon cables connecting the display assembly to the motherboard.
-
In some cases, the suction cup just won't adhere to the screen! You could use a heavy duty suction cup, or duct tape to pry off the screen. However, if you do not plan on replacing the screen, I do not suggest that you use duct tape.
-
Lift the display to a 45 degree angle.

Step 6
¶
-
If the cables are all fine, or making sure the cables are firmly placed does not work, check the dock connector for any broken pins, especially the areas I highlighted with the circular red markers. If any pins are broken, you might want to buy new cables, because repairing these pins requires a lot of experience and precision tools.
-
If this STILL doesn't work, check the pins on the cables connected to the home-button (marked with a red marker in second image.) Again, if any pins are broken, you might want to buy new cables, or a new home-button, because these pins are very fragile and hard to fix.

Step 7
¶
-
If any cables or pins are broken , you could buy new cables, as mentioned before. However, if the home-button screws are broken or missing, or the home-button is completely broken, you might want to buy a new home button assembly. This assembly is displayed on this step's adjoining image.
