A new bug found this week my Griffin Concepts/ Springfield iPhone repair, was when activating 'Airplane Mode'. It appears that when this is activated, or when the SIM Chip has been removed, the iPhone can not only not pick up valid signal, but even crash and reboot!
Symptoms:
iPhone 4 - activated Airplane Mode. iPhone appeared to have frozen for a few minutes, and then rebooted on it's own. After later tests I found that music that was playing while activating the switch would continue playing, until the iPhone 4 reset itself. Even after reboot, the iPhone would not seem to pick up signal. On the occasion that it would (after disabling Airplane Mode of course) no phone calls could be made, texts be sent, or received. Troubleshooting steps: Reset Network Settings (Did not work). Reset All Settings (DID WORK).
iPhone 4 - Removal of SIM Chip, and putting it back in: No service, or iPhone shows service without the ability to place or receive calls or texts. Again, the only successful method was to reset all settings (resetting network settings did not work)
SETTINGS > GENERAL > RESET > RESET ALL SETTINGS
