Users looking for an iOS 4.1 jailbreak for the iPad, iPod touch and iPhone have found an answer with limera1n, a beta from software developer Geohot.

Geohot has beaten the iPhone Dev Team and the Chronic Dev Team with the release of the update. Currently, the limera1n only works on the Windows operating systems and lets users run unsigned codes to gain access to the Apple iPhone firmware. The capability allows users to utilize unapproved installers, thereby making applications that were not offered on the Apple App Store available.

The jailbreak, which is reported to be an unpatchable and untethered release, does not support the iPhone 3GS. Rival developers claim that limera1n will re-lock iPhones. There have also been reports that the jailbreak has not undergone proper testing and may cause problems with the current firmware of devices.

Apple's legal counsel is arguing that the jailbreak is a copyright violation.
