Hii,

so apparently, after those steps, my phone wouldn't work, BUT:

installed the patch -> upgrade to 1.1.2 -> jailbreak 1.1.2

now it works.

don't know why, but I'm glad it is working!

I had the same problem as you did two nights ago. I downgraded my 1.1.2 OOB to the 1.1.1 firmware and had no signal. I upgraded back to 1.1.2 and jailbreaked and the signal finally started coming in.

I got it!
My OOTB 1.1.2 - Week 47 is now Activated and Jailbroken!

But I can't upload files to the iPod, what is wrong?
Shouldn't I use iTunes?

This is because your iPhone has a 1.1.2 baseband. If you want to use 1.1.1 you have to use 'BB Downgrader (1.1.2)' in the unlocking tools.

Here is a guide to help you do this:

I have a 04.02.13_g too .. Has anyone came up with a solution to unlock this version yet ?

click on "Install AppSnapp".

Up to here everything worked fine with me, but when I click on "Install AppSnapp", then the iPhone returns very quickly to the Activation screen, and apparently nothing has been installed, so I can't get rid of the Activation screen. I tried it several times, and, yes, unfortunately I have a 04.02.13_g.

What may be wrong? :confused:

You are wrong. If you were able to downgrade the baseband on a new OTB 1.1.2 iphone you'll be able to unlock it !!!! But the new bootloader won't allow you to downgrade it , this is the reason why OTB 1.1.2 are still unlockable. The method described in the post you mentioned only works with the 3.9 old bootloader.

My 2 cents,
