Well, if didn’t go as smoothly as the 1.1.4 jailbreak with ZiPhone on a PC but I finally JBd my upgraded 2.0 iPhone.
Sure, instead of 15 mins or so it took 4-5hrs with no JB on the PC. Finally gave up and did it on a Mac. Took about 30mins in all.
So now, I have the “best of two worlds” with third party and the Apple App store.
Not too painful. Written on my iPhone.
