    I tried a flathead screwdriver.. Didn't quite work out well...

    I'm on my way to the store.. Maybe try to find something that'll work.

    As well as purchase a few other tools I may need in the future..

    I personally would start working with a clean iphone.. Just because I'm nitpicky about things like that.

    I don't think it matters that much to be honest. All that may matter from what I've read is.. You need to be on 1.1.1 not 1.1.2

    i am definitley not opening up my iphone im just waiting for the software unlock this method is too risky and with my lack of luck i could probably do something worse than bricking the phone, not taking my chances waiting for the soft unlock thats it....hope it comes out in a couple of days now that they found the 1.1.3 seckpack =D

    but first few questions to confirm what i think i know:
    1) in the tuto it says connect testpoints before running iunew but when do i release exactly? is it when output is:

    "TESTPOINT WORKS: 55
    Press any char, then hit enter after testpoint has been disconnected
    x"

    2) after process done the iphone becomes exactly like a 3.9 BL 1.1.1 otb right? no probs and no future problems upgrading and what not right?

    hopefull i get answers b4 i get to his house and get tools ready exciting times.

    thnx
    1) Release testpoint when it says "Testpoint works" yes - it should only take a second or so from iunew is executed until you can release the testpoint.

    2) Yes, exactly like OTB 1.1.1. You can just follow the tutorial at http://iphone.unlock.no/ to jailbreak and unlock it after you have downgraded bootloader.

    3) A guitar pick can be used, or any other very sharp plastic things. You could use a tiny screwdriver also, but you may bend/scratch the metal casing a little.

    Just tried it (not exactly this tutorial, but the way on Geohot's blog, which looks quite similar), and it worked. OTB 1.1.2 iPhone now running BL 3.9, which allowed me to unlock it with AnySIM.

    The hardest part is definitely opening the case, the rest is quite simple (especial because it wasn't my iPhone, it was a friends one :-) ).

    One advice: don't run ienew over wifi, just use the terminal application: I did it over wifi and the Phone crashed after (during?) running ienew. So I had to do a reboot after running ienew but before iunew. After reboot I had now wifi, the iPhone complained that it's damaged and need repair, and (worst of all) bbupdater -v showed a "resource busy". I tried to run ienew and it worked as expeded, but after restore to 1.1.1 still no baseband (iPhone still complaining "need repair", bbupdate -v show "resource busy). A restore to 1.1.2 rescued me: after that, the baseband was working again, including wifi and i could continue unlocking the iPhone.

    So, if anybody finds a easy way to open the iPhone's housing, this is a nice way to get the "cool" 3.9 bootloader... but i took me about an hour to open the iPhone, causing serveral injuries of my fingers.

    dpmpc, i am wondering wether to try it or not... Does it involve a high level of electronic knowledge? I don't know how to do the needles thing, how much cables from one to another...

    By the way, what have you used to scrape the test point? I'm quite afraid of messing it up ending with a broken phone.

    Thanks
    (sorry for the english)

    I murdered my fingers =/

    Only left one scratch on the black antenna case. It took me almost 30 minutes just to get that off

    Still haven't gone through with the tutorial.. I just wanted to see if I could get the case off.. and seeing as I got it off, the next time around should be a breeze.

    I have my needles ready.. The only thing I don't have is a wire to connect em to. So anybody with an idea of what I can use.. I'm all ears.. Btw are the corks necessary? Can I use something like tape instead? Or any other suggestions for alternatives.. I'd be glad to hear them.

    Just wanted to share my experiences with this so far.

    Getting the black antenna cover off was fairly easy. I used an exacto knife and carefully pried up right above the dock connector till I heard the snaps, then I slowly popped out the rest all around the corner on each side.

    The exacto I used had a 3/4 inch angled blade, the tip was pretty thin so it was easy to get under the plastic.

    As for the metal backing, I have yet to get that off. That is the hard part so far. screwed up and put too much pressure on the side (without the buttons) and now I have a bit of a bend in the metal. I had the exacto under the cover and tried prying it outward, that's not a good way to go. I'm going to try the card method until I get the actual iPod tool. Seems like lifting up the cover with a razor blade is probably the best method.

    Anyone else share anything on this?

    probably the hardest thing to watch out for
    1. cutting too deep in the testpoints
    2. deforming the metal backing
    3. static

    cutting too deep is a real problem that you may be able to fix by putting something in the break to reconnect it

    deforming the metal...... well you might be able to lightly apply pressure to form it back close to normal.... best way to remove this is to use multiple tools and equally appling pressure

    static discharge... is the killer here, if you make an arc your screwed
