Help! iPhone says "No SIM card installed"

[xpxixpy]

Hi.
My iPhone has been working fine but since last night I've not been able to use the phone or Edge. When I try to use the phone it says "No SIM card installed". On the upper left of the screen it says "No SIM." I turned the iPhone off and back on to no avail. I also removed and inserted the SIM card.
Anyone have any suggestions?
Thanks,

You know the exact same thing happened to me yesterday... I had my phone about a week and no issues, then all of the sudden I wake up and it said "No Sim". I took it in and out a few times with no luck, then I went to the AT&T store and got a new SIM - went through the activation agian (which only took like 2 mins) and it was fixed. Maybe the heat from the phone damages the sim card or something. You should get a new sim and it should be fine.

My phone did seem especially hot last night. I attributed it to my leaving Wi-Fi on for hours even though I wasn't literally using it (some of this time it was in my pocket or I was charging it). In general, should the iPhone not be stored in your pocket?

I'll call my AT&T store when they open to see if they have the iPhone SIM card.

It is the same sim card they put in all of their phones. They will have one.

I always leave my phone in my pocket and in the rubber InCase, Ill see if it happens agian. They will have a sim just go there, the iPhone uses a regular AT&T sim card which they have a ton of.

I doubt it is because of the heat.

It is not uncommon for cell phones of all makes and models to get the "Insert SIM" Message. I got it on my blackberry, slvr, razr, and multiple cheap flip phones.

Take your phone by the AT&T store and tell them it says "Insert SIM" and they will replace it with a new one. You'll be in and out in a few minutes.

As a follow-up, I got a new SIM card, reactivated my iPhone through iTunes, and everything is working fine. Thanks for those that helped earlier today when I was very concerned.
The AT&T manager said that mine was the first iPhone to have a SIM problem she knew of, so hopefully it was a very isolated incident.

Yes, activation was very quick (< 60 seconds I think).
