Hi Guys, I have just got my iPhone and purchased an unofficial composite cable which apparently only works if I'm running OS 2.0 ... I've been looking around Google and I have come to the conclusion that if I jailbreak my phone it will only me to use this cable without any issues. Now before I go ahead I need some advice from you guys: If I jailbreak will it let me use this cable? Whats the worst that can happen? Would it be easier to downgrade to OS 2.0, If so how would I go about this? Will my homescreen look the same? And are there any other benefits to jail-braking? Thanks for you time guys, I look forward to you replies P.s I'm currently running the latest OS version.
