Im planning on using Ziphone also. What version did you unlock? Did you upgrade to 1.1.4 before you unlocked it?
Actually, I probably did it backwards but it worked so I don't care.
Downloaded and installed iTunes 64-bit (I have 64-bit Vista)
I downloaded Ziphone 2.6b.
Connected iPhone to dock/PC
Loaded up Ziphone and clicked "Do it all!"
Waited 4 mins...
After it was done, I loaded up itunes and clicked restore. This basically updated my phone to 1.1.4.
After the update was done, I ran Ziphone again, clicking "Do it all!" one more time.
Waited 4 mins...
That's it? It's done?! Yay!
