    Go back to cyida and press  “Restart Springboard”Thats not possible. When you go back to cydia you come in the install screen from sam

  • 04.11.08 Unlock

    Update 2 : If you don’t have your Original SIM, try to get out of  “invalid sim”… you to “get searching” while last steps of activation if have gevey SIM maybe help full to select carrier!.

    update 3 : SAM maybe overloaded! keep trying. if you getting no service , USE SIM Card that provide a constant Data … some cards Data activated as requested by Carrier! and check pre settings. Roaming data must be ON

  • Raider-333

    Its not working. I does everything until I have put the iphone in airplane mode to respring the iphone after unistalling SAM. The iphone doesn’t want to stay in airplane mode. When I turn it on, it turns off by it self. And I tried to keep going and respring it, but when the apple activation appears it doesn’t says “E” and it doesn’t accept the SIM card.

  • Alen Čobić

    I couldn’t get E on the activation screen. It only shows wifi networks. Stuck at 12. step… :/

    You need ultrasn0w after all is said and done. Ultrasn0w doesn’t support 4.10.08 bb. I’m ready to buy Gevey Sim 2.

  • Kiteboss

    you might want to hold off on the Gevey solution,because it’s a hardware solution which cannot work on all the worlds networks. See the instructions at applenberry

  • Fpsnwork

    Gevey Sim WILL unlock bb 4.10.08. Waiting for release date CANT WAIT. I am a T-Mobile user!

  • Lumche

  • Deorpc

     Go to Carrier OFF AUTO and it will manually search for your network operator. I did managed to get my operator but i can’t make any call.

  • Ray

    Does anyone can unlock it (4.11.8)? i can’t unlock with this method at all. pls hlep

  • guest

    this is meant to unlock iphone 4 ios5 w/ bb4.11.08

  • artur machado

    no.. i try everything… the only way that i could was before everything turn off the auto search!!

  • Moises

    hi, i followed ur instructions, but a few steps are really confusing.  How can U unistall SAM and the press the HB without doing Respring and then go back to do Respring, it doesn’t  make any sense.  Something is missing along the way.  Also, the word CARRIER doesnt comes out with the original SIM, ATT,  this must be tested by u guys, pls let us know.

  • Radwan Kamhaz

    i think this is just bullcrap.  just did this and im stuck at activating your iphone screen which is kind pissing me off. been on it for 5 minutes using my bros att sim card. im calling gay on this one.

  • reda

    hi and thanks for the try

    please can anybody explain this manipulation in an easy way please
    and what about ***SIM card with constant data available*** what does he mean

    thank you

  • Carlosavila5th

    It does not work step Seven doesnt work. You can’t see the carrier and If you skip it none of the other steps will work.

  • Sergiysm1

    thats not working,wait for gevy for 4.11.08 may be in aweek or two

  • Sai Zhou

    u can try to use gevey sim or original sim to select carrier manually……worked for me, but stuck after step 10 though…….

  • Sai Zhou

    just mean any active sim card support mobile network….. i assume any sim should be fine, unless it is deactived by the carrier

  • Alfakire2000

    is someone to translate these steps into French thank you

  • Sam Audi

    Hamzah said it’s working for Model # MC318LL in UAE

    You need to restore your phone from iTunes or redsnow. Try putting it into DFU mode (press home button and power button together for 15 sec than let go of power button).
