MuscleNerd has successfully jailbroken an iPod Touch 4G running the iOS 5 beta that was released yesterday. Limera1n is a bootrom-level exploit, so Apple can’t patch it with new firmware (only hardware), so the real test will be an untethered jailbreak. MuscleNerd notes that Cydia is working fine, but tweaks will need to be updated for iOS 5 compatibility. There is no ETA on an untethered jailbreak, but it’s possible that the Dev-Team will save any exploits until new hardware is released in September.
