Thanks for that tip. It works with IOS 7.x I had the same problem after replacing the power button and sensor circuit. No Wifi - no mobile signal. The phone (4S) could see my Wifi network but could not get connected. I had to set a static address and then it immediately got connected. Then the time/hour was automatically set. After that I re-inserted the SIM and it asked for the PIN code. But it continued searching for the mobile network. As for WiFi, the device could see the different available operators but could not get connected. I selected one manually and it got connected then reactivated the automatic selection. Everything is fine. Thanks again.
