Nate True over at cre.ations.net quickly followed up last week's release of a software-based jailbreak for PC iPhone users with a version for the Mac. As with the Windows edition, this jailbreak allows users to run 'unofficial' third-party applications directly on their iPhone with 1.1.3 installed.

The 1.1.3 upgrade, as with previous iPhone firmwares, disabled this capability, extending the cat-and-mouse game Apple's been playing against hackers ever since the iPhone launched back in June of last year for another round.

Remember, jailbreaking an iPhone could have negative consequences on your device and Apple, which doesn't look kindly on them, won't be sympathetic should you run into trouble. So be careful.

In fact, you may want to wait until Apple unleashes its iPhone software developer kit (SDK), which is due next month and will finally allow developers to create Apple-approved native software. Once the SDK is out the door, official versions of these types of applications will probably appear pretty quickly.
