Apple's latest creation—the iPhone 4—features a MEMS gyroscope within its pretty shell. But how does that little chip work, and what does it do?

We partnered with Chipworks to bring you an in-depth look into the science behind these micro-scale gyroscopes.

We have also completed an iPhone 4 repair manual with step-by-step repair guides to fix your own iPhone. We currently offer many iPhone 4 parts already.
