Same thing happened to me. This happens when the phone does not get reception. When that happens the phone goes into no service and says "sim card not installed". The solution is to take out the sim card from your iphone put it in another phone and make a phone call. Then take the sim card out and put it back in the iphone and make a call. At first you will see it will still say no service, but when it says calling you will see that after a while (6 or 7 seconds) the bars come up and it will display your carrier name.

the new sim card is connected with having an iphone account. when you say it is officially unlocked.
does this mean that AT&T unlocked your phone?
what i think your saying is that if you have 2 sim cards, one that is in use and the other is a spare you cannot use both. at the same time.
the sims are standalone, to use a spare sim it has to be activated by the carrier, thus disabling your original sim.
when you change sims you will need to reboot the phone that will not change.

SOURCE: SIM card not supported in itunes
what you need to do is put your iphone in recovery mode then wait until itunes reconizes your iphone. it should say itunes has detected a iphone in recovery mode choose restore and that should take care of the problem, (if you backed up your iphone b4 you updated it) and if that doesnt work your still in luck because the dev team put out a new jail for 2.2.1 n lower try jailbreaking it using quickpwn hope this helps

I too have had the "no sim card installed message. What has always worked for me is to go into settings and put the phone into airplane mode for about ten seconds and then switch back to regular mode which causes the phone to reconnect to the ATT network. The sim message goes away. This is also a good fix for when your phone isn't connecting to 3G or showing an "E" instead of 3G.

The phone is locked to Apple and needs a Security code to unlock it.
When you place a new or a existing SIM card from another phone provider into your mobile phone and it asks for a Security code then :-
This phone is locked to the original mobile phone provider. You need to contact this mobile provider to ask for the unlock code (security code) for this phone. You need to provide proof of ownership etc and the phone's unique IMEI number which is located inside the phone under the battery. They use this number to generate the unlock code for your phone.
They should provide you with instructions on how to enter this code into the phone.
Once you unlock the phone, then you can insert a new SIM card in this phone or sign up with another phone provider using this phone.
You could ring the phone provider and ask for the unlock security code because you are going overseas and wish to use your phone with a prepaid SIM card from another country.
The other way to get your phone unlock is to use a phone unlocking company on the Internet, they usually charge a couple of Dollars for their services. Use Google and search for “Security unlocking code”.
