Redsnow 0.9.7b4 Jailbreak iPhone IOS 4.2.1 excludes USBmuxd From Process
Now this particular update on RedsnOw 0.9.7b4 is very simple one, which simply excludes the use of USBmuxd from the iPhone IOS 4.2.1 Jailbreak. In previous version RedsnOw 0.9.7 beta 3, the process includes the USBmuxd within the process. But the Jailbreak iPhone IOS 4.2.1 remains Untethered. The Tethered Jailbreak is expected but it is more likely to have Redsnow 0.9.7 final for Tethered Jailbreak but it is only a speculated view of mine.
Only because the beta versions are moving out very fast, which give hint of release of final tethered Jailbreak of iPhone IOS 4.2.1.
So guys if you use Redsnow 0.9.7 Beta 4, you will not have to use USBmuxd in the Jailbreak Process. And the rest of the process will remain the same.
You can follow the process of iPhone IOS 4.2.1 Jailbreak with RedsnOw 0.9.7 Beta 3.
For Windows Users you should stay with RedsnOw 0.9.7 Beta 3 and for Mac Users you can download Beta 4 but there is no update on Redsnow 0.9.7 beta 4.
