Will this work if the phone originally came with 1.0.2 was unlocked with anysim102 THEN upgraded to 1.1.1 and unlocked with anysim 1.1?? Or does it have to be a phone that came from the box with 1.1.1??

It works on any phone as long as it did not come 1.1.2 OTB. But you must be on 1.1.1 when you do this guide, so if you're on 1.0.2 then update to 1.1.1 first.

Like I say in the OP, 1.1.2 is a lot smoother and faster. Up to you.... And yes there is always a risk in doing anything in life but as long as your follow the instructions you'll be fine.

Back to 1.0.2 from 1.1.2 out of box? If so, then no. The bootloader is a new version in 1.1.2 OOB which prevents unlocking until the dev team finds an exploit.

Dude, we just tried it and it worked

sweet.

Guy at work just bought a new iPhone and it was 1.1.2. We bought the phone right down to 1.0.2 (software, firmware, modem baseband etc). we had to use iEraser/Putty and all that stuff to do this. Modem firmware was being reported as: 03.14.08_G. Phone worked fine when jail broken (AT&T SIM).

Then we used iTunes and bought the phone up to 1.1.1. The modem firmware was now reporting as: 04.01.13_G. We jail broke the phone and it worked fine with an AT&T SIM.

We then ran your instructions and we now have a fully unlocked 1.1.2 iPhone. Modem firmware is being reported as: 04.02.13_G.

We have a Virgin UK SIM in the iPhone and it is currently connected to T-Mobile.

You da man!!

If this is true, then you are the world's first. Can you please give a detailed description of how you did it?

Dang it, ignore me man. Turns out he didn't get it to work and had rolled back to 1.1.1 and anySIM'd it (he wants to use it in the UK). That is why the Virgin SIM was running. I thought it was running under 1.1.2, but it was running under 1.1.1.

Sorry man.

I'm gonna go smack him upside the head!!

So when you first bought it it was 1.1.1 and not 1.1.2 correct?

There is a method to return a new - out of the box 1.1.2 back to the 1.1.1 baseband firmware. Please check the other 1.1.2 jailbreak posts. There's like 5 of them now.

I actually have a link to the method in the OP (http://iphone.unlock.no/#how-to-downgrade-1.1.2) but that still won't unlock it because the bootloader is new for OOB 1.1.2 phones. Downgrading just the firmware and baseband won't help it. Simply stated, an OOB 1.1.2 is unlockable at the moment.
