How to Install Third-Party Apps on Your New iPhone or iPod Touch

If a new iPhone or iPod touch found its way under your tree and you just can't wait until Apple officially supports third-party application development to extend its functionality (who can wait until February?), it's time you jailbreak your favorite new portable device. We've covered two methods for doing so already, but that feisty Apple keeps on changing things up, and the latest firmware (which all of you new owners are likely running) requires a bit more finesse before you gain access to the throng of great apps that have already been developed for the iPhone. So today we're jailbreaking that iPhone or iTouch of yours to open it up to the wonderful world of third-party software.

NOTE: I've only tested these instructions on my iPhone using a Mac, so I can't absolutely guarantee the same level of success on the iPod touch or Windows computers. However, the software was made to jailbreak either the iPod touch or the iPhone on either Windows or Macs, so it should work fine on either. That said, I'll be referring to the iPhone through the rest of these instructions. If you're looking to install apps without activating your iPhone with AT&T, our pals over at Gizmodo have covered that.

UPDATE: It seems that there have been mixed results for some users attempting to downgrade from the 1.1.2 firmware. The downgrade appears to be working for some, not for others. If you have trouble downgrading to 1.1.1, you can simply restore the current 1.1.2 firmware and everything should be back to normal, but unfortunately you won't be able to install any third-party apps. I'm very curious to hear what kind of luck others are having with this, so if you give it a try, let's hear your experience in the comments.

UPDATE 2: Since this article published, the 1.1.3 firmware has been released and jailbroken. Here's how it works.
