Hey, I've unlocked my brand new iPhone with anysim 1.1 and followed the really ultimate guide http://www.hackint0sh.org/forum/showthread.php?t=12817 .

Everything worked fine and I got it to work on the first attempt. Now that firmware 1.1.2 unlock is out I want to upgrade.

Someone posted this method

I can confirm there is no need at all to go back to 1.1.1 at all!!

From 1.1.1 Unlocked I did the following:

1) RESTORE to 1.1.2 (download the 1.1.2 file)
2) Immediately downgrade straight to 1.02
3) Jailbreak 1.0.2 (ibrickr) and activate (Paycay)
4) Install apptap via Ibrick
5) Install BSD, Community and open SSH
6) Drop the anysim1.2u onto phone and set permissions as 750
7) Install Octprep (YES IT WORKS ON 1.02)
8) Unlock Phone in 1.0.2
9) UPGRADE (NOT RESTORE) to 1.1.2
10) Jailbreak

DONE!

Forget about going back down and up thru 1.1.1 - its a waste of time totally!
When I unlocked my iPhone I didnt really know what I was doing but the guide was really good. Now can someone tell me exactly step by step what to do because the other guides Ive searched for are not well explained.

My iPhone baseband is 04.01.13_G

Thanks!
