After spending about 30 minutes on this forum I've come to the conclusion that this information is scattered in various places but as far as I can tell a) it is complicated to understand for a beginner, i.e. it has not become clear to me whether all benefits of jailbreaking will be supported under 4.1, or what is the best software to chose to do the jailbreak. b) the information provided about this in various threads seems inconsistent/not up-to-date/centered around older iOS'es or older iPhone's than the iPhone 4. Since the iPhone 4 is the most rapidly selling phone, and the majority of people looking at this forum have already upgraded to iOS 4.1, I am wondering if anybody can post the fastest as well as the most reliable route here, together with a brief description of which benefits of jailbreaking will be available to those of us who already upgraded to 4.1. Thanks.
