I dropped my iphone and the earpiece stopped working. After 2 weeks of using the phone via speaker phone mode I got tired of the situation. Visited the apple website and balked at the $150 charge to mail my phone in to them. Googled fixing iPhone and ifixit.com came up. I easily found instructions and after reviewing them with the pictures decided to fix it myself. I ordered all the recommended parts and they came in 2 days.
It took me an hour to slowly take apart my phone, tape down the small parts to a board and label each part by step. It took 45 minutes to put everything back together. Could not believe how small the pieces were. So glad I taped things down.
Take the phone apart on something light colored so you can see any pieces you drop.
Tape all the pieces down and label.
I took a break every time I could not get a screw in the hole to avoid frustration.
