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.
wait… do u mean they are trying to come up with something? or the talk about an unlock is fake?
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.
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….
Thanks Stephen. Will keep my ears open lol
We start with the velvet glove Dawn… If they haven’t figured it out in a month we bring in the hammer… F@#k MTV, I want my IPhone unlocked….
Hey Stephen. Any luck on the unlock as yet.
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
