    Hello ,
    My sister just sent me an iPhone 3GS White 16 GB which is locked to AT&T .
    She thought that I'll unlock it myself but I do not know what to do . I don't know what version is it running on and what software should I use to unlock it .
    Any help , links to basic tutorials would be appreciated .

    Cheers ,
    Tanuj

    Depends on your firmware SETTINGS > GENERAL > ABOUT > Version ?

    Google 'Blackra1n' and 'iClarified'

    UK O2 users can unlock via here

    Hey man,

    I was in a similar situation a few days back but got helped out and read up on it. Basically I wouldn't bother jailbreaking your phone if you have the newer bootrom.

    Basically if you have the old one then you can jailbreak it....but...If you have the newer one then you can only do what's called a tethered jailbreak which is like a normal jailbreak but if your phone runs out of battery or crashes and you need to restart it then you can't wake it from sleep without a computer, a usb cable, and a copy of blackrain.

    So I'd advise you to first find out what bootrom you have :D you do this by putting your phone in DFU mode:

    http://www.iclarified.com/entry/index.php?enid=1034

    once it's in DFU mode do the following:


    on PC:

    Start->Control Panel->Device Manager

    In Universal Serial BUS Controller, you will find Apple Mobile Device USB Driver

    Right Click and go to Properties, go to Details tab and select "Device Instance Path" from the drop down list box.

    In that information, u will find [iBoot-359.x] at the end.

    on mac

    Click on your HD > Applications > Utilities > then System Profiler

    From there look in your USB serial Bus bit and you should find it there.

    (obviously your iphone needs to be connected, I know that a bit pointless mentioning but you never know who might not haha!)

    When you have found out what your boot rom version is post it here and I'll try and help you some more :)

    Oh yeah my bad, Jailbreaking and unlocking....not entirely the same thing ^_^ My advice was for if you are jailbreaking it, if unlocking it then I'd follow gix1s advice :]

    lol this is funny, this newbie whose posting advice is wrong about everything. installing blackra1n jailbreaks your phone. in order to download the blacksn0w unlock, you need to install blackra1n. therefore you will have a tethered jailbreak. so its just better to wait and leave it in the box.

    I dont know the version and as the phone is locked it doesn't seem to turn on as well .
    So I can't open the homescreen as well . I can just see the itunes icon on the screen atm .

    Thanks for your reply . I just did what you said and I found out this -
    Serial Number: CPID:8920 CPRV:15 CPFM:03 SCEP:03 BDID:00 ECID:0000001B3A19B5CE IBFL:01 SRNM:[88943RXS3NQ] IMEI:[012027008217514]
    And I'm not able to put my phone to DFU Mode .


    What about my iPhone version . I don't know what version its running on .
