In the immortal words of Proffesor Farnsworth: Good News Everyone. Those pesky 4.6 iPhones remained firmly locked down until just hours ago. The now world famous teen-superhero George Hotz (or to use his alias: GeoHot) has done what he himself described as the impossible, he unlocked the 4.6 bootloader. This is beyond merely amazing, this is near miraculous! He has given a brief description of what to do in his blog post (here) and it is remarkably simple. This means that any iPhone bought since Apple introduced 1.1.2 in USA or the iPhones in UK, France and Germany are now SOFTWARE (no need to do any internal iPhone modification) unlockable. George Hotz is the sole person responsible for this, not the iPhone Dev Team or Elite Team, one single person. I urge you now to donate whatever you can to this great guy (paypal: geohot@gmail.com). Read on for the less-than-detailed instructions by Mr. Hotz himself.

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  

This release is no thanks to elite/dev
I wish they would share like the old days.
I don't believe everyone in the team is like this, but come on guys.
