HT1430 What to do if the message shows "cannot activate iphone" after updating ios5?

After updating to ios5, got the message "no sim card".   I turn off and restart, then reset language, country or region, connect to itune, "cannot activate iphone"  I dont know what's going on?

There are several possibilites:
Your security software (antivirus and firewall) is preventing iTunes from communicating with Apple's Activation server, gs.apple.com.
You have a redirect in your hosts file for gs.apple.com. Open the hosts file and delete any lines that contain gs.apple.com. For the location of the hosts file, on a Mac it's /etc/hosts, on Windows it's c:\windows\system32\drivers\etc\hosts.
Your phone was hacked or jailbroken to unlock it from the carrier it was locked to, and updating it the phone became locked to the original carrier. For this there is no solution that can be discussed in an Apple forum.
