Antwoord op "What screwdrivers do I need?"Could you be a bit more specific? I don't know exactly what you're repairing, but you did put iPhones as the category, so I'll stick with that. For most iPhones, you'll need a pentalobe screwdriver and a #000 Phillips driver. You can order these individually from iFixit, or get an essential/pro tech toolkit which will also include any and all other tools that you'll need to perform most repairs.
