Before disassembling your iPhone, be sure it is powered off.
Apple has recently substituted the two Phillips screws with 5-Point "Pentalobe" screws. If your iPhone 4 has 5-Point "Pentalobe" screws instead of Phillips, please refer to the second picture.
Remove the two 3.6 mm Pentalobe screws next to the dock connector.
During reassembly, we recommend you replace the 5-point screws with equivalent Phillips screws. Our Liberation Kit provides the tools and screws needed to replace the Pentalobe screws with Phillips screws.
The 5-Point Screwdriver should only be used once, as it has the potential to strip the screws.
