You didn't think the folks at iFixit would simply teardown the iPhone 4 and call it a day, did you? They've now gone the extra mile and done a detailed teardown of the iPhone 4's gyroscope with a little help from Chipworks. That's of course a MEMS (or microelectromechanical system) gyroscope and, according to Chipworks, nearly identical to an off-the-shelf STMicroelectronics L3G4200D gyroscope, which is actually what they used for the teardown. What's more, they also went even further and put another gyroscope (not used in the iPhone 4) under an electron microscope just to illustrate how incredibly complex and minute the structure of MEMS gyroscopes are. Head on past the break for a glimpse of that, and hit up the link below for the complete teardown.
