Redsn0w 0.9.6b4 has been released for Windows and Mac operating systems. This what you have to know.

  1. It’s compatible with 4.2.1.
  2. Tethered for all devices except for iPhone 3G, 3GS (old bootrom) and iPod touch 2G (MB).
  3. This is what the Dev-Team said about the “tethered state”:

If you’re on an iPhone3G, old-bootrom iPhone3GS, or non-MC ipt2g, life is easy. redsn0w installed an untethered jailbreak and so nothing below applies.
“Tethered” does not mean you cannot boot at all without PC/Mac assistance.  If you have not installed any tweaks that hook into important programs like SpringBoard or CommCenter, your device will actually boot. However, jailbreak programs like Cydia won’t work (and Cydia may still have a white icon).  Also, certain built-in apps that had to be moved by Cydia will fail (Safari being the most noticeable example).
If you’ve installed MobileSubstrate tweaks that hook into SpringBoard or other important programs, your boot will actually fail (you’ll get stuck at the Apple logo).  You need to use redsn0w to “Just boot tethered right now”.
