The Dev Team has commented on Geohot's multiple iOS device jailbreak, limera1n, released yesterday. A bootrom-level Jailbreak for iPhone 3GS (2009/2010), iPhone 4 (2010), iPod touch 3 (2009), iPod touch 4 (2010), iPad (2010), and theoretically Apple TV (2010). which was released yesterday and it's fair to say it hit the community like a small yield nuclear blast:

Limera1n uses a different exploit than SHAtter, and in fact covers more devices. Although some may question geohot’s dramatic and competitive style, he obviously does have considerable skill pulling this together in just over a day (although he’s had the underlying exploit for months). Credit also goes to @comex, who provides the untethered aspect of limera1n via another one of his growing list of kernel hacks.

The release of limera1n has (hopefully!) averted the burning of 2 bootrom holes at once (both his and SHAtter). Releasing SHAtter now would be a complete waste of a perfectly good bootrom hole in light of limera1n, and so it can be held until Apple closes limera1n’s hole. While there’s no guarantee that Apple won’t also close SHAtter by then, it provides a ray of hope for devices after Apple’s bootrom respin. Meanwhile, look for an alternate implementation of the limera1n exploit in greenpois0n (and possibly other tools), where it should undergo more testing too.

While exploits are how Jailbreak payloads are delivered, they're also security risks that enable any other type of payload delivery -- including malware if bad guys decide to go after iOS. That means Apple has to patch them either in new firmware or in hardware revision that fix more base-level exploits.

The Dev Team also points out limera1n doesn't appear to be well tested or polished yet, but that Geohot has a history of iterating and improving his releases quickly.

Check out our Jailbreak Forum for help and more information on limera1n and other Jailbreaks. And let us know, do you like this newly competitive, somewhat dramatic Jailbreak landscape or would you rather the various individuals and teams coordinate things better?
