A group of amateur developers has ported the Linux operating system to Apple’s iPhone and iPod touch devices. Members of the iPhone Linux development team revealed in a blog posting that they had installed a working version of the Linux kernel on the handsets. The software must be installed by the user, and exists largely as proof that Linux can be ported to the handset. The researchers noted that several major features, such as sound support, touchscreen capability and wireless networking, had yet to be figured out.
