Iphone 4 does not recognize simcard at times.

Hey,

Every few hours, or maybe once a day, my iPhone suddenly comes up with "Simcard is not installed". I am going to the genius bar today, but will they replace it? How can i prove it is a problem?

Have you restored your iPhone 4? Or replaced the micro sim?

This happened to me and I had to get a new iPhone 4. But my iPhone would have service for about 2 minutes then go out. I would have to turn airplane mode on/off or reboot my iPhone to get that 2 minutes of service. I restored lots of times and even replaced my micro sim twice. I went to the Apple Store and the Genius thought my popping the sim in and out fixed the issue because I got full 5 bars in the store.
