Most certainly this is a hot subject for the do-it-yourself iPhone addicts. People are willing to risk all to gain in notoriety.
A few days after announcing a first method to jailbreak the iPhone, one second is proposed by the dev team iPhone. It has a principal advantage of not using any potentially illegal means to arrive at this result. This new version preserves Baseband (firmware modem) intact, which makes it possible to have an unlocked iPhone that can use Turbosim. However, this causes problems with the system of localization.
If you go to the forums of Frenchiphone you will find that there are still many problems with this method as well as problems of installation. We advise you to wait until these issues have been clarified before installing it yourself
