The Raspberry Pi website brings to attention the work done by Dave Hunt. David has built a fully-functional mobile phone using a Raspberry Pi as its main component. While the device appears to lack additional smartphone capabilities you'd expect, the fact that he built a working mobile phone with a touchscreen dial-pad in a relatively small package using off-the-shelf components, is still very impressive.

The PiPhone is a remarkably simple build, with a Sim900 GSM/GPRS module (which you can slip a SIM card into — you’ll still have to pay for your calls) talking to the network and doing the heavy communications lifting (making calls, and hanging up; sending texts and dealing with data); an on/off switch, a converter to make the LiPoly battery output 5 volts, and one of Adafruit’s tiny TFT monitors. You’ll find a typically thorough writeup on Dave’s website, with a parts list (he sourced everything from Adafruit and eBay), although he hasn’t uploaded the code, which he currently considers a bit hacky, to GitHub yet; please do, Dave, because we’d like to have a play!
