I just spent 200 dollars and bought my iphone 3g off ebay and all I want to do is unlock it! My firmware is 2.2 and baseband is 2.30.03 which i completely don't understand and have no idea how the baseband was changed and not the firmware. Maybe im doing something wrong in tattoos steps but I can never get the bootloader information to show up after i type in that command my no sim changes to searching and then my phone automatically cuts off. So I'm really not even sure what my bootloader is. I know you guys are sick of hearing these dumb questions but I am desperate and need any help I can get and in the "dummy" form, not that smart with all of this. please and thank you for you guys time and effort!

    If I update my FW to 2.2.1 , does my BL update too? Because my BL is now : 5.08
    So will it update to 5.09 ? Or does it stay still on 5.08?

    3. Type in: cd /var/root
    4. Type in: chmod 755 BBUpdaterExtreme
    5. Type in: launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist
    6. Type in: ./BBUpdaterExtreme queryversion

    after the "launchctl unload ..." you should get the searching in the top
    do the next command
    and you should see something like the pic i posted above
    continue on if you see "ICE2_BOOT_05.08_...", if not that then you have 5.9
    if you do continue and your iphone restarts carry on from here
    1. Type in: su
    2. Type in the password: alpine
    3. Type in: cd /var/root
    4. Type in: chmod 755 BBUpdaterExtreme
    5. Type in: launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist
    6. Type in: ./BBUpdaterExtreme update -f ICE2_02.28.00.fls -e ICE2_02.28.00.eep
    7. Reboot Device


    I hope this helps you.
    and that you have the 5.8 not the 5.9


    do i tap return after everything i put it, like include the slashes? or do the slashes stand for return? just confused about the launchctl unload and the getting the searching and then doing the next command...oh and also i cannot seem to put my files in var/root or whereever you put them mine always end up in the private folder of var. thanks sooo much for your help though!!

    I can't seem to find it...

    Found it and it didn't work, as of right now I just want to know my baseband...is it 5.8 or 5.9? And I can't find out it won't let me it always says something about the directory not found...it was bought back in sept of 2008 so I'm guessing it is 5.8 but who knows...

    yea just type it in
    case matters, put the slashes (/var/root), hit return at the end of each line
    yea putting them in /var/root or /private/var/root just as long as when you type the command in make sure you go to the specified location (i mean the command that is cd /var/root)

    Three UK works perfectly fine for me. Make sure you have 3G enabled at all times as Three require it to be on.

    I'd do a clean install of 2.20 and see if it works.

    Umm I have a quick question.
    I saw in multiple places that if my iPhone was manufactured before Sept. 2008 that it would have Boot Loader Version 05.08.
    Well, I checked it the other day and it shows that it's 05.09. The iPhone was purchased Aug. 2008 so that got me thinking..did some of the updates change the Boot Loader? I know that it's nearly impossible, so I'm kind of lost..

    The bootloader will not have changed.
    BL 5.09 was introduced around Sept 08, yours must have been one of the first.

    Run the downgrader if it works have fun it not just wait.

    the downgrader will not hurt you iphone if it is not 5.8

    hope it works for you.

    ^^Exactly. Sept. 08. My phone was manufactured along with the first 3G's. It makes no sense.

    ^I have ran it. "Getting EBL Version" Times out whenever I try to do it. Everything else is OK except that.

    I hope OS 3.0 comes out soon with a software unlock method because this i-smartphone sim unlocker blows. After 24 hours the iPhone is saying "no SIM" whats the point if I only have the phone working for 24 hours then I have to put it back into a T-Mobile phone? Pleae tell me OS 3.0 is coming out like June 1 :P

    Quick update.

    Apple patched BL 5.08 to 5.09 in week 28 which is the week the 3G was released but existing phones with BL 5.08 were still being sold until September 2008.
    Apple are very quick at patching holes when they are found which is why the Dev Team will not release anything until FW3.0 is officially released - or it will be closed down before then.
