I am trying to replace the screen for my iphone 4 and bought the new pentalobe screwdriver and managed to get the first 2 screws out. Now my phillips head #00 is too big to get out the next level of screws. I even bought a new set that has a #00 and #000 phillips head and both of them were too big. Any ideas? Thank you for the information!!
iPhone screws are Phillips #00, I however often use a Phillips #0 for my repairs, go figure. The iPhone screws are very shallow, the tiny drivers often hit the center bottom of the screw head making them useless. In the sets you have try the #0 driver. Or you may have to buy another #00. Good luck.
