Well, I guess it is time to lose my JB applications and do a full restore. Pity, I do like having a mobile terminal; but I think having a more optimized OS is worth the loss.
So now that the USB drivers on Mac OS 10.5.6 are purposefully designed to cause an error for the "Pwnage" series of programs, what will everyone do if a new 2.2.1-compatible JB procedure is released? Flash under Windows? Or does using a powered USB hub work? I've always been a little sketched out by the idea of flashing something with a USB hub--it seems that most hubs really, really suck when it comes to real-time connection reliability, latency and constancy of USB bandwidth.
