Problem is those pentalobes. Once I got familiar with iPhone 4 display change (usually takes 10-15 minutes to swap one), the main problem was to get open that little glass box. I invented couple of bicycles from old screwdrivers, pins and clippies but it was always the most timeconsuming thing. So I thought to get real and order that Pentalobe from you. !&&*, I use your guides a lot so why not. And got that tri-wing and Air Pentalobe too for a good measure.
Oh, happy days .... these screwdrivers arrived promptly and let me tell you, they are sweet and look so professional. All technicians envy me now. In my mind. No, they do. Opening and closing iPhone 4 has became a walk in the park. Or screw in the park. No ... wait.
I heartily recommend to order pentalobe NOW. Not tomorrow, but now. Because then you will have pentalobe tomorrow or day faster and you will get home sooner, repair iPhones quicker and get a little bit closer to World Peace or Total Domination (whichever you want to achieve) So please, in the name of all that doesn't suck, get help, get the pentalobe from iFixit.
