    You bought one of the new 3GS 8GB iPhones? You need to tell us what firmware you're on.

    All basebands for 3.1.2 are unlocked and jailbroken. Use those guides.

    Redsn0w jailbreaks 3.0 and 3.0.1, so use this guide

    http://www.ihackintosh.com/2009/07/h...th-redsn0w-08/

    Then use this guide to unlock with ultrasn0w

    How to Unlock Your iPhone 3GS OS 3.0 With UltraSn0w | Update guides
    alright i gotta problem, i wanted to clean the iphone first and decided to hit the erase content and settings, and now the freaking phone is just on the screen that says install valid sim to activate iphone, and u can only make emergency calls, so i took it through redsnow which by the way ur link for it was not valid for windows so i had to download the newest version somewhere else, but still no luck because i get stuck on the redsnow page that wants u to go into recovery mode by holding power and home but mine wont do and therefore the next button won't illuminate so i can move on in redsnow, any ideas?

    ok this regard everything is good to go, my freaking usb cable wasn't working (i know im an idiot!!!!!) lol
    let me ask u something else now that i'm jailbroken and unlocked on 3.0 i should be able to use redsnow and ultrasnow and move on to 4.0 right?

    U have a 3GS? U have to make sure u have the old bootrom. Also, know that once you upgrade to 4.0 you won't be able to downgrade anymore

    yeah its a 3gs and i was able to jailbreak and unlock to 3.0 with the links u send earlier today, thanks.
    but i'd like to go to 4.0 now, however redsn0w_win_0.9.5b5-5 keeps saying it doesn't recognize the ios 4.0 for 3GS any ideas?

    No, you don't do it like that. You have to update through official iTunes update. But I warn you, you HAVE to check to see if you have the old bootrom, otherwise you will NOT be able to jailbreak 4.0 and will not be able to use your phone

    I think you screwed yourself to be perfectly honest. If youre already on 4.0 youre screwed, if not, dont use Redsn0w

    If youre on 4.0 you need your SHSH blobs to downgrade to 3.1.x and jailbreak it with Sn0wbreeze or Blackra1n (3.1.2 only) then use Sn0wbreeze or Pwnage to upgrade to a pwn'd 4.0.

    If you are still on your 3.0 fw, do what adp said then use sn0wbreeze to create a custom 4.0 fw to shift+restore to upgrade and jailbreak with.
