The good news for current RedSn0w users is that all you have to do is rerun the new version over your existing jailbreak in order to receive the fix.

For those of you without access to a computer, or who don’t feel like bothering with RedSn0w again, you can always install the latest version of Corona that we posted about earlier.
The Dev Team goes on to say that like the update to Corona, the latest version of RedSn0w includes a fix for the sporadic launchctl issues as well.
Of course, if you’ve still yet to jailbreak your iPhone 4 or other A4 device, check out our RedSn0w page for the full scoop on how to do so.
If you already know how, mosey on over to our downloads page to download the latest version of RedSn0w — 0.9.10b4.
