Hi there
A friend of mine upgraded his iphone to 1.2.0 he came to me and I downgraded it back to 1.1.4 and unlocked (with downgrading the itunes metod then unlocked with liberty) worked like a charm.
Then he when home and don't know wat he did but he upgraded it again to 1.2.0 and I tried the same medod like before but i get no network in the end . . . any solution . . .?

Follow those steps:

if when trying to unlock with bootneuter you get an error, follow the steps there:

I solve no signal

http://hackint0sh.org/forum/showthread.php?t=46640

I restore apple firmware 1.1.4
after i use iliberty+ but i read that not payload found.
I retry to use iliberty+ and It install payload.
At finish my Iphone doesn't have signal also.
I wait about 5 minute and my vodafone logo reappears.
Now It work perfect.

I think it's a problem from all iphone ziphoned by a old version of ziphone in 1.1.4 and upgraded to 2.0.
The signal heven't in 2.0 also.

i am not sure if i can be of any help but have you tried to revirginize your iphone and tried to downgrade the baseband as the signal problem lies in here if not try out the freezing the iphone method which is literally placing your iphone inside the freezer for a short period of time if thats the case your problem lies in the hardware... and on some case the unlocking process...

I had the same exact issue. All funcitons of the phone working EXCEPT telephone.
No signals...ATT or Tmobile Sims tried. Go to http://iphone-freak.com
Download his modified Ziphone program (IT WORKS) Check on the boxes (in other words you want these to take place) DOWNGRADE BASEBAND and DEBUG BOOT. Let it do it's thing and when you are done you will see the wonderful signal bars (If your sim is already in)....Let me know how it works for you.
