I unlocked my iPhone a few days ago. Everything worked. Today I synchronized it with iTunes, after that I did not get any signal bars. I did a full restore with iTunes. Everything worked perfectly again, but after the first sync I'm back to no signal bars.
HELP!

After trying to make a call I get "No Service" instead...
Should I try to unlock it again?

did you put it back in jail before syncing?

No. But if it's in jail Installer.app won't work.

EDIT:
I tried again. Jailed it this time and now it's working.
But Installer.app gives me this error: "Error during install script execution!". Do I have to jailbreak it for every time I want to install something?
Is there any workaround for this?

I sync my iPhone when it's jailbroken all the time. I have also synced with iTunes many times since I did the software-unlock. I did the manual non-gui unlock. I still run iTunes 7.3.2 aswell... I do not dare upgrading to 7.4.x just yet.

Maybe I can downgrade iTunes to 7.3.2 then? Can someone post a link?
