No SIM message on iPhone 4

Well, that didn't last very long. After just a couple of days, it started happening again. I have noticed a pattern. After driving in the car for a few minutes, with the iPhone in the cup-holder, I will get the No SIM message. Also noticed it when I had the phone on the boat this past weekend. It appears that the SIM card is not as firmly seated in this phone as it is in previous iPhones, or any other phone for that matter. Any sudden movement or vibration will cause the SIM to lose contact.

I'm going to the Apple store today to get a new phone. This is absolutely unacceptable.

Went to an Apple store yesterday and swapped the phone out for a new one. The guy at the Genius bar didn't even bat a eye. He ran some diagnostics on it and nothing came up bad, but when I explained how many times I was getting the "No SIM" message, and that AT&T had already swapped out the SIM card, he just gave me a new one. So far, so good.

Well, its been just over a week now and I'm not seeing the error any more. Must have been a bad batch of phones. The new one is working fine.
