Just replaced a broken screen and now the phone says "No Service". It detects the sim card and I was able to go into home screen after inserting sim card and plugging into iTunes. But it does not detect any service networks. It says "Searching...." then goes to "No Service"
I know there is one on the 4 but the 4s is different
Is this a good question?

Make sure to wipe down all metal components with isopropyl alcohol, and screws per tare down.. Finger oil can effect signal. Also AT&T iPhone 4 has an important diode near the bottom of the logic board ya want to check on iPhone 4. Make sure you have the correct grounding screws in.

Make sure the small wifi cable on the bottom speaker assembly is connected properly to the bottom of the logic board near the power cable.
