I saved my nephew's life (aka his iphone)

我的问题

His iPhone 4S volume buttons did not work at all, his mute switch was unreliable and he was going through earbuds like crazy.

我的修理方法

I first tried replacing his volume buttons, hoping for an easier fix but no luck. I bit the bullet and gutted his phone to replace the headphone jack/ volume control cable. It took about two hours, including the amount of time I spent crawling around the floor looking for tiny bits I dropped, twice.

我的建议

I had to go back into the phone with a q-tip wet with windex to clean the connectors. Be sure to clean the metal parts where the tutorial mentions it. Works perfectly now. Awesome!
