4.2.1 tethered reboot question
I've searched around and haven't had any luck finding a good answer.
I just did the 4.2.1 jailbreak last night on my iPhone 4. I know now that I have to have it hooked up to my pc to when I reboot.
Do I need to have itunes installed on a pc in order to perform a reboot? If I need to reboot while at my office, for example, I don't have (and can't get...) itunes installed.
Can I simply put the firmware file and redsn0w on a usb drive and use it for a reboot?
Thanks in advance
