Everyone’s favorite muscle-bound nerd brought iOS fans great news on Tuesday: iOS 5 has already been jailbroken. The Dev Team’s “MuscleNerd” posted on Twitter that he has successfully jailbroken Apple’s iOS 5 software using Limera1n. Right now his jailbreak is tethered, meaning the device must be connected to a computer each time it is booted, but this version of the jailbreak will never reach consumers so it doesn’t really matter. MuscleNerd says the exploit used to jailbreak the iOS 5 beta will still work on the final release version, so iOS users can sit pretty knowing the latest version of the operating system will likely be jailbroken immediately following its release this fall.
