I have an iPhone 2g that won't turn off. When I try to turn it off, it just reboots. I've done a bit of research and apparently the dock connector is faulty. It also shows the "this accessory is not made for iPhone" message when nothing is plugged into it.

I'm not too bothered about this a the phone itself still works, but when I try yo jailbreak and unlock with redsnow, it states that the phone must be plugged in and switched off (in capital letters).

Since my phone can't be switched off, how can I redsnow my 2g iPhone?

Thanks!
