Soon after fourth-generation iPod touch released into the beta release, the hacker confirms in a tweet that iOS 5 was jailbroken. But unfortunately, Limera1n iOS 5 Jailbreak is ‘tethered’ right now, which means that a device shut down will require it to be connected to a computer running limera1n in order to restart to jailbroken state.

Also on Twitter, the hacker warned iPad 2 GSM and CDMA owners that iOS 5 betas are to be avoided if they’re hoping for a potential iOS 4.3.3 jailbreak. Both the iPhone Dev Team and Chronic Dev have long announced plans to issue reliable jailbreaks for the second-generation Apple tablet, but the tools are yet to reach end users. Musclenerd’s warning should not be interpreted in any way other than: install the latest iOS
only if you don’t plan on jailbreaking.
