Dev Team is making great progress in developing a decoding solution for iPhone 4, it seems that MuscleNerd and planetbeing have succeeded yesterday si azi to "play" a little with the iPhone 4 baseband and test some commands used in the previous versions of the decoding software. For now, they are far from finalizing the decoding solution, but they will definitely make one and release it probably this month, after iOS 4.0.1 will be released by Apple to correct the bugs in iOS 4.0.
Surely this decoding solution will be available after the one of jailbreak, for which I foresee a later release date than that for iOS 4.0.1. I say this because a release before 4.0.1 could result in the loss of a good exploit.
