Just days after initially jailbreaking the new iOS 5 beta, a hacker group releases a version of the popular Redsn0w utility for others who want to do the same with the mobile OS.

Apple's new beta version of iOS 5 has been jailbroken for the second time this week, now opening the door for users to jailbreak their iOS 5 devices using the latest version of the popular Redsn0w tool.

In a blog post today about the new jailbreak, the iPhone-dev Team, a group of hackers that target Apple devices, announced that it has released a tethered redsn0w jailbreak for iOS 5.

As with the group's first jailbreak of iOS 5 earlier this week, the redsn0w jailbreak will let users install Cydia, which allows them to use apps unapproved and unsanctioned by Apple.

However, the iPhone-dev Team cautions that the redsn0w jailbreak does come with several caveats.

Only a tethered jailbreak is available, which means that users who reboot their devices will need to run redsn0w again to force it back into jailbroken mode. The team also cautions that those who've unlocked their phones should avoid the redsn0w jailbreak and the beta of iOS 5 itself for now as it could break their unlockable basebands.

For now, the new redsn0w 0.9.8b1 jailbreak only works on Macs (Windows users are currently out of luck). And the following devices are supported: iPhone3GS, iPhone 4 (GSM and CDMA), iPod Touch 3G and 4G, and the original iPad.

The beta of iOS 5 is available only to developers, and the iPhone-dev Team is saying that only iOS developers with registered IDs can get past the activation screens. For non-developers, the team is asking them in no uncertain terms not to pirate Apple software.
