    Semi thethered Jail is possible for 4.11.08 , no unlock by now… How ever everyone were talking about an unlock before 01.12.11 than the first Wednesday of this month … All f@ke.

  14. Dawn says:

    Well if ask me this program does the same as the others basically jailbreaks the phone but offers NO solution for the 04.11.08 baseband problem.

  15. Stephen says:

    Let’s remain patient and appreciate the creative minds that will figure this BB 4.11.08. It’s a great challenge that I’m sure one of theses creative folks will figure out….

  16. Dawn says:

  17. Stephen says:

  18. Dawn says:

    Hey Stephen. Any luck on the unlock as yet.

  19. Stephen says:

    I have given up…. You made up my mind…. I have moved on to obsessing over other things I can’t do anything about…. Have a wonderful holidays and New Year… Stephen
