Yesterday the general public learned what a pentalobe is. You might be asking yourself why you’d need such a thing, but if you’re like Uwants member mkmarken, then you’d want it to disassemble your iPhone 4 in order to strip the black coating from the inside of the Gorilla Glass enclosure with a little paint thinner. Just because you’re continually discouraged from opening your device doesn’t mean you can’t make it easier for everyone to see what’s inside. [via TUAW]
