  16. hey man it worked! but it also did not give me the time and it says "exit safe mode" in the top instead of the time, this is kinda frustrating! I first downloaded ultrasn0w from cydia, and that didn't work, and now I do this, it worked but it says exit safe mode, what's happening!!? I removed ultrasn0w from cydia and now both the unlock and the exit safe mode disappears! Help Please!

  31. I followed your method for unlocking my jailbroken (with redsn0w)  iphone 3g with ios 4.2.1 and baseband 5.15.04
    Well, it does not unlock my iphone. In fact it causes springboard to crash every time, and yet
    when I touch "Exit Safe Mode", a windows appears that says
    We apologize for the inconvenience, but springboard just crashed

    Mobile Substrate /did not/ cause this problem> it has protected you from it.

    Your device is now running in Safe Mode. All extensions that support this safety system are disabled.


    PS: I followed your method very carefully and precisely as you state it.
    It did not unlock my iphone, as I am unable to make any calls.

  32. While the phone was in safe mode, I started cydia and I saw that
    2 packages needed updating.  They were Mobile Substrate and Ultrasn0w.

    I updated both of them and rebooted.

    The phone nol onger goes into safe mode and springboard does not crash.

    BUT.....

    The phone remains LOCKED!!! Cannot make any calls.
    and.... yes, I do have a good activated sim inserted into the sim slot.
    Same sim works just fine in my other cell phone.

  34. Hey, I just completely removed Mobile Substrate and Ultrasn0w from Cydia & springboard stops crashing... :)

  35. I Think of your
    talents as the things you’re really good at. They’re like personality traits.
    For instance, you may be a very creative person, or a person who’s really
    good at attending to details or a person with a gift for communicating. Your
    talents are the base for any successful business venture, including a
    home-based business.

  40. If it's not working, you need to change your baseband (firmware) to the iPad one, the version that comes with 4.2 is too resistent to unlocking. Redsnow has an option to use "iPad firmware".


    If you're getting safe mode, update Mobile Substrate from within Cydia. Other apps need a later version than the one you're using.
