According to GeoHot's web site: "The current method involves taking apart your phone and doing some complicated soldering, with a high probablity of a bricked phone. Although after the phone is unlocked all the hardware can be removed. We hope to find a software unlock very soon." GeoHot also uploaded a video in you tube showing his unlocked iPhone. Though this might seen quite unbelievable at the moment since several Scams about unlocked iPhones are flying around, GeoHot has a very good reputation on these matters which could be attested by the Dev Team's forum members."

Roland Piquepaille writes "Physicists from the University of Illinois at Urbana-Champaign (UIUC) have improved the performance of solar cells by 60 percent. And they obtained this spectacular result by using a very simple trick. They've coated the solar cells with a film of 1-nanometer thick silicon fluorescing nanoparticles. The researchers also said that this process could be easily incorporated into the manufacturing process of solar cells with very little additional cost.
