    What week are both your phones? You can check the fourth and fifth digits of the serial number.

    Both 1.1.2 OTB
    Then we can very well say that phones with week > 47 can't be downgraded

    I picked up a week 47 today. I'm not sure if I'll try anything with it yet. I think I'll wait to see if anything happens with the week 49 within the next week or so.

    Do we really have evidence that there's a production cutoff where this problem starts? It looked to me on some other threads that later weeks have worked. Is it that they didn't downgrade to 1.0.2 and just worked the BL downgrade from 1.1.1?

    The BL downgrade and its consequent unlock can very well work on all 1.1.2 OTB phones (and possibly 1.1.3 OTB when the newest firmware and its secpack is released). The current issue here is that, after getting stuck with a bricked iPhone after running 'ienew' over SSH/WiFi and not having any kind of local terminal installed on the iPhone (which was my case), losing WiFi and having to restore the phone, the only real possible solution to have a local terminal was to downgrade to 1.0.2 which is jailbreak-able from 'the outside' without needing to prepare the previous system (as is the case with both 1.1.1 and 1.1.2, when not using the jailbreakme.com method which is out of the question because of the no WiFi issue), and realising that it is impossible to downgrade an US 1.1.2 OTB > week 47 iPhone because of the eternal 'Waiting for iPhone' message, on whichever combination of hardware (PCs, PPC and Intel based Macs), sofware (iTunes/OS) and DFU methods.

    We could conclude that on > week 47 something else has changed on the phones (I don't know if it's the bootloader version) that prevents the phones from being downgraded to 1.0.2.

    Regards.

    Good point. If you have mobile terminal installed, then you are able to complete. I think I'm getting threads mixed up now. hehe

    I have two currently, (a week 48, and week 49)

    Both can be easily downgraded to 1.0.2 [OTB1.1.2 w/ BL 4.6] using DFU mode and iTunes 7.5

    I think your problem is screwing up while doing the hw unlock??

    I think some are, socal. But we're also seeing some 1101s and other errors without h/w procedures, I think.
