iPhone Dock Modification

Here is a quick set of my personal modification to my old iPhone dock, to be compatible (fit) with the iPhone 3G. Do this at your own risk, as I can't be held responsible for any voiding of warranties or damaging of products. I would suggest reading this entire description before starting.

Tools used:
Clear packing tape
Sharp tool (I used a cheap Maxam folding knife)
Small flathead screwdriver
100 Grit Aluminum Oxide sandpaper (found in the Paint isle of any home improvement store for about $2.50)

Step 1: Cover the male (inside cradle) and female (on back of dock, along with the Line out input) dock connectors with the packing tape. Don't want plastic shavings to ruin the connectors!

Step 2: Start carving out the inner sides and back of the dock with the sharp tool of your choice. Cover your word area with something for easy disposal of all the shavings. Carve for 5 minutes at a time, and then take the tape off the male dock connector to test out your progress as you go. I used the small flathead screwdriver to help me take the tape off of the male dock connector. Don't forget to re-cover the connector with tape after each test. Do not worry about making your carvings even or smooth. We'll worry about that on the last step.

Step 3: Once you think the iPhone sits nicely, test out the connection to make sure your iPhone 3G syncs (taking the tape off of the connectors, obviously.)

Step 4: Reapply the tape to the connectors.

Step 5: Sand down your carvings with the 100 grit Aluminum Oxide sandpaper. This is pretty messy, may want to do this part over a trash can with safety glasses.

Overall, this entire process took me around an hour, including the time I had to run to the hardware store to get the sandpaper. I hope this helps you in saving the time and money it would require to purchase the new 3G dock!
