redsn0w Can Jailbreak iOS 5 Beta 4 for your iPhone

The iPhone Dev Team is back at work, again. Just like iOS 5 beta 3, the latest beta 4 build can be jailbroken by redsn0w, as noted by @musclenerd. This is a tethered jailbreak, and should only be used if you require a tethered jailbreak for iOS 5.

As described on the iPhone Dev Team blog:

Update #4: In conjunction with iOS5 beta4 being released to iOS developers, redsn0w 0.9.8b4 is now available for jailbreak app developers (point the b4 redsn0w at the b4 IPSW). 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.

Since iOS 5 updates from now will be pushed over the air, it will be much harder for people to lose their jailbreaks because–OTA updates won’t work on jailbroken devices.
