No SIM card installed, No SIM, Invalid SIM card

Hello,

I'm getting No SIM card installed on my iPhone 4. I got a new SIM card and 15 minutes later same error. I've reset network settings and also tried a restore with no luck. Genius Bar recommended wiping and starting over without restoring from Backup. Was going to erase mine and start over tonight but....

My wife bought a brand new iPhone 4 from AT&T today... At exactly the same time both of our phones came up with the No SIM card installed message! Her brand new iPhone 4 said the same thing.... This is after I sync'd it up to iTunes, only a few songs and a bunch of apps.

There is something going on with either the network or something with the phone or iTunes causing a problem with the phone. I've almost pinned it to something in iTunes 10.1 because I think this started happening about the same time I updated to iTunes 10.1. Both of us are now on iTunes 10.1.1.4.

iOS 4.2.1 on both phones... Anyone else experiencing similar issues?

Thanks

I am having the same problem. I went to AT&T to get a new SIM card as someone suggested in another thread. Now I still get the same error message, but a lot more often at least once or twice a day. I have done hard resets each time and sometimes it works sometimes it doesn't. Tech support suggested going to the Apple store, but the closes one is about 3 hours away.
As far as iTunes update, I think you are on to something because that is about the time mine started acting up. I am hoping an update in iTunes or the phone software will fix the problem.

I have been having the same issue intermittently for the last couple of months. The first time, I read on here to pop out the SIM and make sure it was clean (I suppose it could get linty or whatever) and that stopped it for about a month. But now it happens a lot the last few days, and often if I put it down while it's in that "No SIM" state, it will lock up and then crash.

Sounds like I need to go to the Apple Store?
