iFixit and Chipworks teardown the iPhone 4’s gyroscope
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.

Christopher Tarnovsky hacks Infineon’s ‘unhackable’ chip, we prepare for false-advertising litigation
As it turns out, Infineon may have been a little bit… optimistic when it said its SLE66 CL PE was “unhackable” — but only a little. The company should have put an asterisk next to the word, pointing to a disclaimer indicating something to the effect of: “Unless you have an electron microscope, small conductive needles to intercept the chip’s internal circuitry, and the acid necessary to expose it.” Those are some of the tools available to researcher Christopher Tarnovsky, who perpetrated the hack and presented his findings at the Black Hat DC Conference earlier this month. Initially, Infineon claimed what he’d done was impossible, but now has taken a step back and said “the risk is manageable, and you are just attacking one computer.” We would tend to agree in this case, but Tarnovsky still deserves serious respect for this one. Nice work, Big Gun.
