    Unhappy No Network After Jailbreaking (iPhone 3GS)

    Hi
    I'm new to the forums and i was wondering if someone could help me.
    I have been a ipod touch/iphone user since the ipod touch 2g first came out.
    Anyways, i have been using my iPhone 3GS jailbroken using blackra1n on 3.1.2 firmware since i got the phone but resently it was not working so i tryed restating the whole iphone prosess again. I then acidently updated to 3.1.3, then wanting my iphone jailbroken again i downgraded my iphone back down to 3.1.2 and got the "error 1015" following a guide that told me to ignore it and go on with the jailbreak, I did. But when i did the phone started up with no service and no network selection in settings. I have tryed using Redsn0w, and blackra1n. Even as a last resort Sn0wbreeze. But i still come out with no signal in the end! Can some please help me???? i want my iphone jb again and i do not know how :S

    When you accidentally put firmware 3.1.3 on your iphone, the process updated your modem/baseband firmware from 05.11.07 to 05.12.01.

    Eventhough you managed to downgrade to firmware 3.1.2 to your phone so you can perform the jailbreak, which you successfully did. However, the downgrade process can only put the OS to 3.1.2 but it cannot downgrade your modem firmware to 05.11.07. Therefore, you will not be able to unlock that phone at the moment. There is NO UNLOCK for baseband 05.12.01 at this time

    If you're using the phone on the AT&T network, you may need to do a reset of your network settings to get connectivity after an OS downgrade.

    As dtube said, 3.1.3 included the 05.12.01 baseband which is (at present) not able to be unlocked. If you're needing to use this phone on a non AT&T carrier and it's not a factory unlocked device, upgrading to 3.1.3 shut the door on you until 3.2 comes out and the respective jailbreak and (hopefully) unlock.

    All though I am successfully Jailbroke my 3g "redsnow" with base band 05.12.01, and I am a ATT paid carrier, My phone is showing no carrier. Is there a way around the No carrier? A way around with a legit paid carrier? Or do I have to wait for the future hack?

    This phone was not activated for me. My sim was activated through Itunes on my mac. I got the phone off ebay and when It arrived it was busted up. I put it back together, I found that it had been hacked and upgraded. They then could not get the phone off "sim card not recognized" So I had to downgrade and re-run the hack to get it back to life.. And then get it out of restore mode. After all that, I got it back up and running and here we are. So I was wondering if since I am on a legit carrier. Is there a way around it? Can the phone just be restored back to original state? Thanks for your help.
