    Just got a 2nd Gen 16gb iPhone that was already upgraded to 2.2 firmware. Am trying to do the downgrade steps to jailbreak/unlock/activate the phone to use T-Mobile. After I restore it in iTunes I get error message 1604. It says "the iphone could not be restored. An unknown error occured [1604]". Previously, with my old iphone, I would click off that message, open ibrickr, and kick it out of recovery mode. However, ibrickr and iliberty do not recognize that there is a phone plugged in. I've repeated previous steps to no avail. Anyone have any suggestions that will help? Am I using old steps to try to correct this problem? Can I leave the firmware at 2.2 and still be able to jailbreak/unlock/activate? I've been trying to downgrade the firmware to 1.1.4. Obviously I am missing a step I am unaware of.

    Someone please helo!! I am getting desperate.

    don't get angry with me, YOU should read the sticky on this forum at the top.

    i believe it starts with:
    "new to the iphone world..."

    become a little more educated to ask the question you need answered because you threw around so many things that didn't make sense that it made it extremely difficult to even grasp which issue you have that is creating a bigger issue

    like for starters, by 2nd gen do you mean 3g?

    Well, it was a typically worthless reply but there's some truth in it. To start with, 2.2 is not officially available and while I haven't bothered with the Apple test systems (and this is exactly WHY I don't bother with their test systems), the Apple web pages that contain them all clearly stated that once you put these systems on your phone, there's no going back. You can put the official 2.2 on a test 2.2 dev phone, but you can't backtrack to 2.1 or whatever directly from the test system. Secondly, a "2nd gen" phone is a 3G but you're describing hacking apps that only work on the original phones, not 3Gs. Additionally, you can't put a system earlier than 2.0 on a 3G phone. Finally, a 3G phone can be jailbroken but it can't be carrier unlocked in software yet, period. There are hardware solutions that I hear work, but I don't personally know and you're not getting any of those for free. So if you actually have a 3G phone, you're probably SOL on a lot of fronts. If it's actually an original (NOT 3G) phone, you're probably still SOL since those beta systems can't be replaced by earlier systems. I'm no expert but my guess would be that you're not going to be able to do much of anything with it until 2.2 is officially released. Then you can put on a real system, downgrade it and carrier unlock it. Maybe a DFU restore would work but having never tried it, I don't really know. Just an idea. I also don't know if you can jailbreak and carrier unlock a test system but if I had to guess, the answer would be "good luck with that!".

    Oh...just in case it really is a 3G, T-Mobile's 3G network uses a totally different, oddball frequency. So even if you do get it working and then working on T-Mobile, the best data speed you'll ever get out of it is EDGE. And not just EDGE, T-Mobile EDGE.
