The technique involves sending only one unusual text character or else a series of "invisible" messages that confuse the phone and open the door to attack. Apple has not released any updates yet. So little can be done, except power off your iPhone to avoid being hacked."

The design uses two major chips. One handles the SPI to MAC/PHY translation for the ethernet jack. The other chip is a PIC24F, which hosts a simple web server and reads files stored on a microSD card. All components run at a low 3.3 volts. Part of the compactness of the design comes from the PIC24F having programmable pins; only four jumper wires were needed. The single-sided SMD design is easy to manufacture at home. Part 1 covered many of the 24F's features and both posts have full code available."
