RedSn0w 0.9.7b4 iOS 4.2.1 Untetherd Jailbreak is OUT!(not supported 3GS new-bootrom)

約束通りredsn0w 0.9.7b4 リリースされました(OS X only)。ターミナルでcommand を叩く必要はなくなりましたが、残念ながら3GS new-bootrom のサポートは見送られました（iPhone側の処理変更はなし）。

redsn0w 0.9.7b5 はBug Fix と、（可能なら）Windows サポートでしょう。

Update #4: The fourth beta is now available (testers ONLY please!). Starting with this version, redsn0w no longer requires you to install and run a separate program for the usbmux (this was a non-trivial procedure for many). It’s okay to keep that program running if you normally use it for ssh anyway. We also think we’ve fixed a race condition in the GUI that was causing redsn0w to crash during the “Preparing JB Monte Files” step. Nothing at all has changed on the iPhone side (where the main issues are still just Bluetooth and Skype).
