Basicly I need help to HOW I can jailbreak my Iphone, it has the 4.1 version as suggested on many websides, but I don't know if it's worth jailbreaking it when I hear that everytime my computer synchs the iphone, the jailbreak will most likely go away..And my computer automaticly synchs the Iphone when I add songs, or just plugin the Iphone to the computer :S

Any advice from people who jailbreaked their Iphone? or people who know about this?

Okay now...I got the hang of the jailbreaking now, I just need to downgrade my Iphone to 4.0 now...I currently have 4.1..anyonw got a link to a tutorial? or perhaps you can explain here
