The iPhone Dev-Team recently released Redsn0w 0.9.6rc7 to help you boot your tethered jailbroken iPhone, iPad or iPod touch quickly by bypassing some of the screens that you will normally see when using Redsn0w for iOS 4.2.1 jailbreak.

We’ve updated redsn0w to include “one-click” support for those of you running the tethered 4.2.1 jailbreak.  Using command-line arguments, you can now bypass the screens you’d normally see as you use redsn0w to “Just boot tethered for now”.

Below are instructions on how to quickly boot your tethered jailbroken iPhone using RedSn0w for Mac.
