Sorry if this has been asked, but I am on iOS 4.2.1 on an iPhone 4 and I know what tethered means. I also know that cydia requires you to reboot a lot as do most jb apps, so my question is do I have to do a tethered reboot anytime I install something and if so should I just power off my phone after installing/updating an app or hit reboot. I tried to jailbreak a few days ago using redsn0w and it got stuck at the apple logo when I rebooted after installing lockinfo. Help!!!
