How connector 3 on the iPhone 3G and 3GS works
I needed to disassemble an iPhone 3GS and there's a lot of guides out there on how to do it, but not one had a good picture of connector 3. People would describe what to do, but without seeing it, it's hard to guess what they mean. I kept poking at it delicately trying to figure out what to do and I was afraid of breaking it. In fact, I started to pick at the wrong side and I almost broke it. So here's some close-up pictures of that connector and how it flips up and down.
