Picked up a used iphone 4s.. white.. 64GB.. good price. Camera wasn't working and the battery didnt hold a charge for very long. Couldn't resist the urge to see if I could fix it. If I couldn't fix it, I could give it back to the original owner, no charge. If I suceeded, I could replace my wifes old 3G.
The repair went great. First, I followed the ifixit instructions and took the phone apart to see if anything obvious was wrong, and to see what I was getting myself into, since this was my first iphone repair. Cleaned the camera contacts, put it back together and the camera (and the phone) worked! Camera cut in and out a few times after that, and the battery was weak, so I decided to take a shot.
Ordered the camera and battery, and a few tools I didn't have. When I had questions, ifixit was great to chat with by phone. Great support.
I'm glad I got the magnetic project mat. I was able to mark what parts went with which step as well as the position of all the screws and parts. Plenty of room to support my verbose note taking style. Never used any of the spare screws I ordered, but enjoyed the peace of mind of knowing that I had spares in case I blew the screws all over the place like I almost did first time I cleaned the contacts!!
If you can change a tire or a hard drive, you can fix an iphone. If you're a tinkerer, you'll probably enjoy it. It really wasn't that tough. Nerve wracking for a first timer, but not difficult.
Another tip: don't overtighten screws. They're really tiny and it would not take much to strip a screw or attachment point.
The magnetic project mat was great. And I liked the idea of having a set of spare screws. Cheap peace of mind.
I find myself hoping I can find another phone to fix now that I've got the confidence I can do it.
