Now Apple brought this pentalobe screw sets first for their battery cover-up in MacBook Pro, but that was in the mid 2009. This they did specifically only on the battery, so that the user is not gonna tamper is battery, he got no tools to do that. But now, they are using the same type of pentalobe screws to screw it up. This is not the only part of the story, they bought similar pentalobe on 2010 MacBook Air to tie up the lower case, there by preventing user to gain any access to terminals, its known that many non-US released iPhone 4 got smaller vesrions of the same pentalobe. Now they have switched production and US versions of iPhone too got the thought-to-be tamper resistant pentalobe screw, but not any more with the Pentalobe screwdrivers. Worst part is, if you take your iPhone to Apple, be it any kind of service they are gonna sabotage you by replacing the existing set of screws with their new “tamper-resistant” screws.
The only intention I see with Apple bringing out such a screwy screw is that they wanna let you off, its only seen on the outside case of your iPhone, MacBook Air and the batteries of your MacBook Pro, but they are not using it throughout each device. What does that mean, they want to keep you off your own hardware. But it doesn’t end that way, pentalobe screwdrivers are to get you in. Get yourself a pentalobe screw driver and you reclaim what you just lost- the access. Its not costly to get a pentalobe screwdriver, you can find lot screwdriver manufacturers in the market coming out with pentalobe screwdrivers.
