  1. who gives a F about unlockin same old firmware on new IOS , have a balls and unlock 04.11.08 or 04.12.01. and stop posting recaps about old 04.11.08 unlocking solution .

  2. Hi

    I have a question. Mine is iphone 4 5.0.1 with 4.11.08. If I update it to iOS 5.1.1 will the baseband change to 1.59.00 ,4.26.08 ,05.11.07 ,05.12.01 ,05.13.04 ,6.15.00 ? If its changing to any of the above bb can i use
    Ultrasnow 1.2.7 to unlock?

  3. please why dont you people come up with an idea on how to unlock 4.12.01
    if they could come up with sam and it was blocked then i think these hackers are close to unlocking it. why dont they just concentrate on unlocking it rather than jailbreaking it. i know millions of iphone4 users including myself are stuck with the 4.12.01 baseband right now. and its embarassing especially when you cant make use of your phone while its getting old.

  4. Come on!!! I bet there are only 30% who still have those basebands and use Ultrasnow to unlock. Most of the ones I know are already using gevey sims and new basebands. Please work on unlocking 4.11.08 and 4.12.01 because that’s the problem of about 50% iphone users. Please!!! It’s been almost a year since I haven’t been able to use my desired simcarrier because of this stupid lock :/

  6. Why the fvck are you all complaining? Be thankful they have released something useful for iphone users with such specs like mine, i’ve been waiting for this for a long time and its worth the wait, for me, why dont you all shut the hell up and wait? Are you paying them? Donating to them? its free to leech, and yet you ask for more, seriously? If you cant wait buy a new phone faggot. Btw thanks.
