Fixing or upgrading Apple devices will become harder in the future as the company started using a new tamper-resistant "Pentalobular" screw across its new iPhone 4, MacBook Pro and MacBook Air devices. Additionally, the company also ordered Apple technicians to replace the Philip screws with Pentalobular screws in every device they service.
"Apple's latest policy will make your blood boil," says Kyle Wiens, CEO of iFixit. "If you take your iPhone 4 into Apple for any kind of service, they will sabotage it by replacing your Phillips screws with the new, tamper-resistant screws. We've spoken with the Apple Store geniuses tasked with carrying out this policy, and they are ashamed of the practice."
But iFixit has found a workaround: a driver that works on the flowery 5-point Pentalobular screw, at least to hack out the screws so that you can replace them with standard Phillip screws (assuming, of course, that you have the right size Phillip screws).
