I recently purchased a dock for my iPhone from a guy on Ebay. It’s not an official Apple product, because $5 is a far better price than the $29 Apple wants for a piece of plastic. All-in-all, its a great little product, and it would be perfect but for one thing; every time I plug my iPhone 3G into it, it mutes the sound.
Of course, given that this dock has a Line Out jack on the back, it makes sense that it would disable my iPhone’s built-in speakers. After all, why would you want your iPhone’s tinny sound tarnishing whatever you plug in the back? However, seeing as I’m using it as a bed-side stand, there will never be a speaker system to tarnish. Here’s how to prevent it from muting your iPhone.
Step 1: Open it up. You’ll need a small phillips screwdriver, about 2.5mm in diameter. Just stab it through the rubber layer on the bottom and unscrew.
Step 2: Using a soldering iron, remove the tiny resistor (Pictured to the right) from the marked location on the PCB.
Step 3: Reassemble and enjoy. :)
