After the last Jailbreak method - for the most recent iPhone 1.1.3 firmware - left many users with less than functional handsets, the general advice has been to hold off on installing it unless you’re confident in your hack skills; thankfully GeoHot has come to the rescue with a method of his own.  Be warned, however, it’s not a one-click-and-you’re-done system, and requires a little command line bashing.

geohot’s 1.1.2 software unlock yes, this is what you have all been waiting for now fixed to support 1.1.3

1. Download these:
gunlock and the secpack from http://iphonejtag.blogspot.com/ or the blog
the 4.02.13 fls from http://george.zjlotto.com/index.php/baseband/

2. Downgrade your phone to 1.0.2. See all the great tutorials online to do this.
Your baseband won’t be downgraded, this is normal.
This will probably work on other versions too, but 1.0.2 doesn’t lose wifi on bb access.

3. Kill CommCenter and run “gunlock secpack ICE04.02.13_G.fls”

4. Reload CommCenter. For some reason my phone was in brick mode. Use the elite team bricktool to get out.

5. Enjoy your 1.1.2 OTB unlocked iPhone

Now who’d have thought it’d be this easy  

Apparently 1.1.3 has been the cause of some aggravation between different teams working on hacking the iPhone, with the previously all-conquering DevTeam coming in for some criticism over not sharing information.
