Jailbreaking OTB 1.1.2 iPhone: “

Not terribly long ago I provided instructions for jailbreaking an iPhone that had been upgraded to iPhone software version 1.1.2. In short order the comments area was choked with questions regarding iPhones that shipped with 1.1.2. Could they also be jailbroken?

Seems likely to me, thought I, but am I or am I not the kind of guy who’s willing to put a few bucks on the line to find out for sure? Turns out I am. I purchased a new iPhone the other day to see exactly how easy it is to jailbreak it without also signing up for another AT&T account (after all, how many iPhones does one person need?). The procedure is not that difficult, but it requires a few extra steps not required of an iPhone that has been updated.

I could regurgitate what I’ve previously written and then include those extra steps but, quite honestly, I think you’ll gain the greatest benefit from visiting modmyifone.com to view its Getting Started iPhone Modding OS X guide. It’s a clearly illustrated, three-page guide that takes you from a boxed iPhone running iPhone software version 1.1.2 to an activated and jailbroken 1.1.2 iPhone. For all intents and purposes, what you wind up with is an 8GB iPod touch that bears a camera and speaker.

(By activated I mean only that the iPhone won’t bug you to activate it as, after you’ve followed this procedure, iTunes and the iPhone will believe that it’s activated. Of course it isn’t so you can’t use it to make calls unless you really activate it.)

I performed the operation on a MacBook Pro running Mac OS X 10.5.1 (Leopard) and iTunes 7.5. Worked like a charm.

The usual disclaimers: If you muck it up, you’re on your own. I performed the operation successfully twice but you may not be so lucky. Also note that this procedure will not unlock your iPhone for the purposes of using a different carrier. This procedure is useful only for installing third-party applications on your phone.
