Redsn0w 0.9.8b4 Released To Jailbreak iOS 5 Beta 4

Redsn0w has been released by iPhone dev-team to jailbreak iOS 5 Beta 4. If your device is Jailbroken you won’t be able to update to iOS 5 Beta 4 using OTA, you must download the full version from  Apple’s developer center.

In conjunction with iOS5 beta4 being released to iOS developers, redsn0w 0.9.8b4 is now available for jailbreak app developers. Remember, it’s a tethered jailbreak right now so you’ll need to use redsn0w to boot into a jailbroken state at each power cycle.
NOTE: It appears that by design, the OTA update that became available starting with iOS 5 beta4 will *not* be automatically applied to jailbroken devices. That’s a relief to those who don’t want to lose their jailbreak via OTA pushes. If you’re jailbroken, you’ll need to use the standard iTunes method to get to iOS 5 beta4.

You can use Redsn0w to jailbreak your device using the previous tutorial.

Remember this is a tethered jailbreak meaning that you will have to jailbreak your device every time the device reboots.
