1.1.2 and 1.1.3 OTB software unlock!

George Hotz has single handedly done the “impossible.” He has released a software unlock for the 4.6 bootloader, aka 1.1.2 otb and 1.1.3 otb. What’s most impressive is that this was achieved within 24 hours after he started working on it. You can read about the entire adventure on his blog.

The best part is that it’s a dead simple procedure. Here’s the procedure:

WARNING!! This modifies your baseband. I take no responsibility if your phone is damaged from this. Please do not email for assistance. You can get help in irc listed below. This script will allow you to unlock your phone with geohot’s methods. If you have success with this method, you should donate to GeoHot.

Steps (can be done on any phone version, 1.0.2, 1.1.1, 1.1.2, 1.1.3):

-Set “autolock” in settings to never: Settings, General, Auto-Lock

-Install the “Geohots Gunlock Script” unlock script package from BigBoss’ Experimental/Beta Repo
(BigBoss’s beta repo is found in sources category inside installer).

-Install BSD Subsystem + Term vt100

-On 1.1.2 or 1.1.3, go to settings, and set AIRPLANE mode to ON

-Open termvt100 and type:
cd /usr/bin
geounlock

-That’s it! Note, you must be on 1.1.2 or 1.1.3 soft upgrade for you to receive signal.

If you’re not on 1.1.2 or 1.1.3 upgrade/jailbreak to get there.

Note to those performing the above inside 1.1.3:
If you get resource busy errors or error 16’s, try repeating the above using Erica Sadun’s UICTL to unload commcenter. You would use UICTL before typing the term commands.

If you have any suggestions or bug reports you can get help in #iphone on efnet or on irc.osx86.hu.
