    Hi

    I have a jailbroken iphone 3GS version 3.1.3 (7E18) with 05.12.01 firmware.

    How do I upgrade it to a higher version 4.0 or higher? Also please suggest which version would be the best for this jailbroken phone.

    Thank u.. :)

    Last I read, Apple is still signing 4.1
    So if you want iOS 4 that's the easiest option.

    Chambone is right. Apple is still signing iOS 4.1 for iphone 3GS.

    till now Apple has released iOS 5.1.1 for iPhone 3GS and it is good for iPhone 3GS. You can update to iOS 5.1.1 easily.

    Moreover if u depend on the unlock then simply use any JAilbreaking Tool to make a custom IPSW and preserve the baseband. u can use sn0wbreeze and Redsn0w for custom IPSW

    I would personally stay with 3.1.3 on your 3GS as I think that OS runs smoother than 4.1 on your iPhone.

    ios 5.1.1

    download redsnow 0.9.14b2 and custom ispw 5.1.1
    go to redsnow extras-custom ipsw this will create a cusotm ipws which you can restore using itunes.

    go to itunes press shift and select restore and choose the custom ipsw created by redsnow.

    After restore go to jailbreak. select both cydia and downgrade to ipad baseband.

    Go to cydia and search for rocky raccoon for unthered jailbreak.

    install ultrasnow from cydia for unlock if your phone is networked locked. this step may destroy your push notifications on your phone.

    A cellphone repair agency in India says they can factory unlock the iph 3GS. Is it possible to do that? Or does a jailbroken phone have to be jailbroken to upgrade the OS.

    If they can factory unlock it without a JB or any hacks then go for it.

    The agency says that they will contact AT&T and get the phone factory unlocked. Is that possible?
