So I had somewhat of a random issue today. My idol is working perfectly then all of a sudden I get the "emergency calls only" warning. Service is completely gone. After rebooting a few times to no avail, I move my SIM card into my Wife's phone...no issues. I move her card into my idol, the Idol doesn't recognize it. I factory reset the idol and it works again. Any idea what the heck may have happened? I absolutely hate factory resets so I definitely don't want to go through this again if it happens in the future. It was definitely a software issue. I just can't figure out why my idol randomly stopped reading my SIM. Hoping someone can help me figure it out as it's driving me insane.
