iPhone 3G unlocked and service with tmobile currently. iOS 4.2.1 BB 5.15.04 Win XP pro SP2 from all the reading online i have hopefully reached the right conclusion. all i want is a jailbreak. since i am already unlocked and have service w/tmobile, i shouldn't have to upgrade to iPad BB 6.15 for the unlock. but i am not absolutely certain. considering all the little things that seem to pop up, i was hoping to get validation either or. if i can just do a jailbreak any suggested program.
