External case screws
The Verizon iPhone 4 uses two five-point "Pentalobe" screws. Apple began using similar screws in 2009 on the MacBook Pro and in 2010 on the MacBook Air. In January, our friends over at iFixit reported that Apple is using these screws on all new iPhone 4s and even swapping out the original Phillips #00 screws if you bring your phone into an Apple store for a repair.
In the past, I've used a narrow flathead screw driver to remove these. If you want a more reliable tool, iFixit sells a custom-built iPhone 4 screwdriver.
