No Sim Card on iPhone 4G HELP please!

So I just had my first call on my iPhone 4G and it dropped it out of nowhere and when I looked down to see what the problem was it said No Sim Card. The phone was working fine throughout the day getting good reception and was responding well to texting but like I said once I had my first call it completely went out on me. I shut it off and restarted it but nothing changed, right now I'm waiting for itunes 9.2 to download and I'm going to try syncing it to my itunes now. I don't know what else to do though. Someone please help

iPhone 4G, iOS 4

I am having the same problem - received the no sim message 5 times yesterday and once already this morning. The airplane mode solution is great to hear about, since carrying around a paperclip to pop out the sim each time was annoying. Hopefully the cause of this problem can be identified soon so it can be fixed - reports from other forums have suggested that simply replacing the sim card has done little to resolve the issue.

This has happened to me four times in the first six hours I have had the iphone 4g. The only way to fix is eject the sim tray or enter and exit airplane mode. This is very no bueno as you you will not receive or can make calls when this condition occurs. I am making a genius appointment. I cannot get the issue to occur based a specific action so this is not going to be fun. . . .This is either a manufacture or software issue.

I am having the same issues with a 32gb iPhone 4 on 02 upgraded and activated yesterday it started happening last night so I just reseated the sim in the holder and it came back. Happened three times again this morning & a restart sorted it for a while but now I just get the no sim message all the time even if I restart or reseat the sim. As i'm at work I cant get to my computer to reset until tonight so very frustrating.

I have spoken to O2 and they claim my sim is ok & I have put it into a nokia using the Micro Sim adaptor supplied and I am getting full signal and no issues
