    If it wasn't for you guys I would not be able to have an iPhone here in Puerto Rico...

    I get better customer support from this website than from Apple or AT&T itself ... it's strange.. but true !!!

    THANK YOU !!!!!

    I tried over and over again 'til I left both buttons pressed for about 10 secs after the screen went blank, then released the sleep button (top) and iTunes recognized the phone, after that the option/alt-restore process selecting 1.0.2 ipsw file. At the end you will get an error but it should be error (1103). after that you are back in 1.0.2 Hope it helps

    tried that and it updated to 1.02 but I still get incorrect sim error

    UPDATE: Not confirmed yet, but for those having the "incorrect SIM" issue after dowgrading, try this (thanks, Doerr)

    Just turn off the phone, take out the SIM card, turn it on, and when its done put it back in.
    I can confirm that this does NOT work for me and I'm displaying the Incorrect SIM message

    What version of iTunes are you using?

    Try using 7.3.2. This version of iTunes has no clue about the 1.1.1 update.
    Available here:

    After installation, place the 1.0.2 restore file (iPhone1,1_1.0.2_1C28_Restore.ipsw) in the following directory:
    "CDocuments and Settings\%username%\Application Data\Apple Computer\iTunes\iPhone Software Updates" (without the quotes).

    EDIT: the link provided is for Windows users.

    Thanks for the straight forward response! I appreciate it. I plan on downgrading this afternoon because 1.1.1 is giving me all sorts of problems, plus, I miss my 3rd party apps.

    I already unblock my iphone and working perfectly . I have a question. Is that truth that the new iphones selling in store at this moment canīt be unblocked, even if you use 1.0.2 firmware version?

    Talking The Downgrading from 1.1.1 to 1.0.2.
    This process does work,

    First be docked to itunes hold the hom and power key til the screen goes blank a couple secs after ur slider disappears for the off

    now keep ur finger on the home button and let go of the power button ur computer stays connected during this.

    now ur computer if windows will detect ur phone at that moment let go of the home button

    itunes should still be open and has detected ur fone and ur screen should be blank on the fone.

    hold down ur shift key and click on the restore button, a window opens find the file update that u downloaded 1.0.2. and select and hit ok. let it do its thing.

    Now u are set, I used jailbreak on mine and everything went back to normal, now I have been using it for 3 days and I just started getting issues with the EDGE, it says no edge subscription dont know why yet but I am looking into it. with the edge out no email or web.....

    My 3 year old sister could do this....

    Hold HOME till iTunes recognizes the phone then release it.

    DO NOT hold it till you see any restore icons (triangle or otherwise). The screen SHOULD BE BLANK when you release the HOME button

    And just to clarify

    HOME is the round button on the FACE of the iPhone

    SLEEP is the rectangular button on the TOP of the iPhone.
    Follow Murfunit's instructions for home + sleep combinations. This is what finally worked for me. Thanks Murf.

    My mac itunes 7.42 failed at the 1.11 upgrade then subsequently failed at putting on either 1.11 or 1.02 using restore. The 1.11 upgrade just basically forced the phone into recovery mode forever. It starts the restore when I try, but it always fails for 'an unknown error (6)' What the heck is going on?

    Also the home button thing doesn't do anything.

    Oh and funny enough, I quit out of itunes one time and the phone comes back up (no yellow triangle or apple), and its working again, no restore has happened no upgrade has happened whatsoever, back at 1.02 with all my files still there. But syncing doesn't work..... so weird. I just want to restore it basically right now and it just won't do it.

    it didnt work for me i follow the instruction and it shows up the errors that u indicated but i still have the incorrrect sim.

    Update :

    even more crazy, while doing all of this one of my mac USB ports decided to freak out that I was plugging in the iphone in and out. It stopped recognizing ANYTHING including the mouse.

    So I finally try another port and voila, able to restore to 1.02.. activated successfully, now to resync my data, move to 1.11, and wait for a new version of installer so I can enjoy my toy again

    downgrade worked perfectly as advertised! I've never used AppTapp Installer for windows b4, worked pretty quick too. Thanks, now I can mod again

    i bought sevral iphones and i got 1 that is 1.1.1 so i compared the imei no's my resaults were if the imei contains 30000 its 1.0.2 it can be unlocked if its 30001 its 1.1.1. for example if its 0112430000***** then its the old update. also if its 01124500***** if you see either the 500 or the 30000 your good but if you see the 30001 dont bother opening and through $40 to return it.

    Note this is a hypothesis i made and worked with over 10 phones!

    please confirm this if any one has other thoughts to it.
