The unofficial iPhone Dev Team will not release a new iPhone unlocking tool until the final versions of iOS 4.2.5 or 4.3 come out, "whichever is last," according to core member MuscleNerd. A beta of v4.3 is already public, but still very much in progress. The v4.2.5 release will be unique to the Verizon iPhone, which launches on February 10th.
