3G does not have SHSH, and doesn't require any. You can downgrade to 3.1.2 without any problem. Search for how..?
 
Try one of these steps:

1. Reset Network Settings
or
2. Turn Airplane Mode on, then take out the simcard, turn Airplane Mode off and put it back in.
or
3. Turn 3g off, usually when you unlock it u have to set it to off. Reboot iPhone.

One of these steps might solve ur problem.
 
Sometime you need to check inside the phone,. some iPhone i experienced the same "NO SERVICE"

Guess what, some iPhone they still have old X-SIM fitted inside, so open up and check whether any hardware mods.

Good Luck!!
