    Hey i followed all the instructions on how to use sam, went through everything and it worked, it went through itunes and i restored from my last back up, only problem is that it still says searching, and after a while it will say no service? what should i do? im 4.3.3 on a 6.15 baseband !
    oh and i believe im on a custom 4.3.3 ipsw firmware

      That’s probably because Ultrasn0w also got wiped out along with the restore you just performed. Open up Cydia, reinstall Ultrasn0w & reboot your iPhone.

    Hello

    Sorry for the lame question: will flashing the above custom ipsw preserve my baseband?

    I currently have iOS 4.3.3 on my 3Gs with 5.13.04 BB (preserved), and now want to roll back to 4.2.1 (blobs saved, thanks Saurik).
    Also, will the above IPSWs have Cydia installed, or I will have to redsn0w it?

    Thanks a lot in advance for the reply

      Yes, it’ll preserve your BB and Yes, it’ll jailbreak and install Cydia for you as well. Make sure that you complete the unlock by installing Ultrasn0w from Cydia.

    Hi,

    What’s the difference between activated and unactivated?

    Cheers,

    Mehul

      If you rely on an unlocked iPhone, download activated. If you have official carrier SIM card and you do not rely on an unlock then download unactivated.
