I know it’s too soon for guessing games but a few hours after the release of 1.1.4 firmware update, I have yet to hear of jailbroken iPhones being bricked by updating. Has Apple finally given up trying to get unlockers? Does it make sense to give up on their cut from the wireless providers from iPhones that were supposed to be operated on exclusive carriers? My opinion? Apple is planning to sell unlocked iPhones. It makes a lot of sense. If users are willing to risk bricking their iPhones just to get out of wireless slavery, they will be more than willing to pay for pricier iPhones that comes unlocked out of the box without going into the tedious and illicit process of software hacking.

It is important to note about the 0.5 that “your iPhone be running a non-jailbroken 1.1.3. IMPORTANT: The unlock ONLY works for bootloader 4.6. When in doubt, don’t use the unlock The actual jailbreaking process will take about 1 minute. If you have an iPhone and would like to unlock and “hactivate” as well (you will get the option when you start the jailbreak, that will take another 2 1/2 minutes.”

iJailBreak 0.5.1 vs. 0.5 – these are similar codes though the 0.5.1 includes fixes to previous bugs and should expand compatibility. A fix for segmentation fault errors and PPC compatibility have also been included in the 0.5.1.

I’m only posting an excerpt from his blog, but afterward you can click the link to go directly to his 1.1.3 OTB iPhone unlock instruction page. Also, please consider donating to GeoHot via PayPal at geohot@gmail.com.

“These instructions assume that you have already jailbroken the particular firmware you would like to be on. This works from 1.1.2 or 1.1.3 firmware! You can find instructions on how to do that here:

Jailbreak 1.1.2: Windows, Mac
Jailbreak 1.1.3: Installer, Windows, Mac
Downgrade 1.1.3: Windows, Mac

Also, you can only follow these instructions if you are on a 4.6 BL iPhone. This means that your iPhone came with 1.1.2 or 1.1.3 Out of the Box. PLEASE MAKE SURE YOU DON’T DO THIS ON A 3.9 BL IPHONE!

IMPORTANT*: You must have enough disk space free on your iPhone to install this package. Otherwise Installer may display a beach ball and then crash to the Springboard. You need space free on your ROOT file system. Your root file system is about 267M-300M in size. Its NOT the 7.3G file system! A tutorial on how to do this can be found here

Finally, you need BSD Subsystem Installed from Installer app (System Category). This most likely will already be installed especially if you did the 1.1.3 soft update…

If you have 1.1.3 OTB follow the downgrade link above to downgrade and jailbreak your iPhone.”

Here’s a hardware unlock for the iPhone. It’s supposed to be safer than the usual method from the iPhone Development Team and the iPhone Elite and it’s way easier. No idea if Brando gives assurances that it won’t Brick your iPhone. It just needs to be attached to your SIM card and off to other wireless providers you go. It only works for v1.1.2. I suppose, it’s another version of the TurboSIM iPhone unlock they use in China.
