Linux4nano has designed a button-pressing Nanotron 3000 to help with a brute-force attack on older iPods. It can press three buttons if needed, operate independently overnight, and should be able to get through 23,000 addresses a day. The Nanobot 3000 works with older models of iPods, but newer models have encrypted firmware updates that can be difficult to test. The Nano Nano can also operate independently, and can be programmed to press three button buttons at once.”]
