Hi,
I know exactly what you're going thru. Happened to me last night when I used ZiPhone to jailbreak my 1.1.3 Out of the Box Iphone.
I think what happened was ......iTunes didn't sync and "activate" after ZiPhoning.
Try this.....
1. restore your iPhone thru iTunes
2. Jailbreak/Unlock using ZiPhone again
3. Leave phone connected even after ZiPhone completes
4. Wait for iTunes to sync to iPhone........
5. After the sync, eject iPhone and ENJOY!!!!!
This is the steps I used and it worked for me. Only thing I can think of that I pulled the plug too soon.
Hope this helped....please hit the "Thanks" button.
