Geohot has done did it again with a complete software unlock for out-of-the-box iPhone’s running 1.1.2/1.1.3.
Instructions are provided within the RAR archive. The procedure involves downgrading back to system software 1.0.2; however, Geohot notes that other versions may work. See here for [older] downgrade instructions. Put your phone into DFU mode to allow the software restore/downgrade; I use iNdependence for that.
If you encounter problems or have any questions — please search or ask in our forums.

Comments (32)Looks like iPhone hacker and hardware guru, Geohot, has done it again by unlocking an OTB 1.1.2 iPhone. It’s not the easiest procedure but you can bet that will follow sooner or later. The process entails downgrading the iPhone’s boot loader via hardware hack. Details and instructions available at the source link. Kudos!
If you don’t know what you’re doing, I recommend waiting for a complete software solution. Stay tuned.

Comments (7)Steve-Jobs.com has released an updated pdf guide of their refined version of Geohot’s hardware unlock. This is by far the easiest to follow, most comprehensive guide on how to unlock your iPhone using Geohot’s method without the messy soldering.

Comments (1)As promised — the steps to achieve a full hardware unlock of the iPhone. Rather than me copy/paste directly from geohot’s blog, just follow the link below. It’s divided into separate blog posts coinciding with his wonderful sense of humour. You’ll laugh, you’ll cry, you’ll potentially end up with an unlocked iPhone.
I must warn you: it’s definitely an advanced procedure not intended for the faint of heart. If you have the skills, or the balls, have at’er. It’s currently the only working method aside from going the Turbo SIM route; however, Bladox remains out of stock. I feel for those less fortunate, really.

My spidey senses are tingling (again)… I can feel a complete software unlocking coming soon.
Kudos George, and everyone else involved.
