redsn0w 0.9.8b4The iPhone Dev Team has released a software update which you can use to jailbreak an iPhone or iPod touch running iOS 5 beta 4. Apple released the latest beta version of its upcoming mobile operating system to developers yesterday.

Redsn0w 0.9.8b4 is available for Mac or Windows. In order to jailbreak your device you’ll need to connect your iPhone or iPod to a computer using a USB cable and follow the instructions in the software, choosing the iOS 5 beta 4 IPSW file when prompted.

The result is a tethered jailbreak. That means you’ll need to plug in your device and run redsn0w again any time you reboot or you’ll lose your jailbreak.

Jailbreaking an iOS device allows you to install the Cydia Store for apps that aren’t available from the official App Store. So far it’s been possible to jailbreak every beta version of iOS, which bodes well for the anyone hoping to be able to jailbreak the full operating system once it’s released later this year.
