    Default What are my option on 3GS???
    Hey guys,

    I have a 3GS currently on 3.1.2 and is jailbroken with 05.11.07 and bl 06.04.

    I want to unlock the phone, everytime i install snow from cydia i lose signal it says no service so i have to uninstall it.

    I had it unlocked on previous versions.

    Can i upgrade to 3.1.3 or 4.0 and jailbreak/unlock???

    If so can someone point me to a guide out there? I have been looking for a while and cant find anything.

    Thanks in advance.

    If you have the old bootrom, you can use custom firmware iOS 4
    If you have the new bootrom, you cannot restore to Cfw iOS 4
    So it all depends what bootrom you have.

    Your service has nothing to do with Bootroms, uninstall blacksnow. Then go to Cydia and add this repo ;
    cydia.pushfix.info and install Blacksn0wRC2.
    Reboot. .. see if you are getting any signal and remember to turn off the 3G.

    I already had the BlacksnOwRC2. I just removed it with 3G off and reinstalled it. Looks like it works for a few seconds but then it goes to no service again. I see that there is a Blacksn0w forRC2 for OS4, should I upgrade and use that? Will that work or put me in a worse situation than i am already in?

    Only old bootrom can be jailbroken at iOS 4.0. To find out by serial number, if your 4th and 5th digits starting from the left of your serial number is less than or equal to 40, you can safely say that you have the oldbootrom, otherwise they are all new bootrom. You can also check by using USBview, make sure you check the config decriptor and hit F5 to refresh and your Iphone must be in etiher recovery mode or DFU mode to be able to see the info.
    I should advise you not to upgrade to iOS 4 , I myself decided to downgrade back to 3.1.3 now as I have found most of Cydia & Rock apps don't work anymore and I can't access my paid apps anymore.

    Have you edited your hosts file to point to Saurik Server :
    For pc : Cwindows\system32\drivers\etc\hosts.

    Open up hosts file and add this line at the bottom or last line

    " 74.208.10.249 gs.apple.com " without the quote and saved it.

    If you are a vista/win7 user, you have to run it as Admin, only then it will allow you to save it.

    You have to reboot your pc

    Then do the Shift + restore and browse to the firmware you want to restore.
