iPhone 4 runs without SIM card after installing iOS 7/7.1.1

After installing iOS 7 and all the latest update by using iTunes on my iPhone 4 I now have the problem that when starting the phone without a phone card I get the information that the SIM card is blocked and that you have to slide to unlock, the same information you usually receive when such a card is inside. Once unlocked the code screen appears asking for the PIN. The iPhone runs after having entered the PIN and you can open and work with all the apps which don't need an access to the internet like Calendar, Notes, Settings etc.. What has gone wrong? Can anybody help me please.

iPhone 4, iOS 7.1.1, 32 GB

The SIM is only actually required during activation. And if you want a connection to a cellular carrier, of course. Once activated, the SIM can be removed and the device can be used as if it were an iPod Touch. This has always been this way.

I'm not entirely clear on what you think is wrong.

It's a strange situation. The SIM used is pin locked and what is really funny, is that the iPhone only accepts the pin from the SIM I usually work with. If you insert a friend's SIM for example, switch the phone on, try some apps, put it off, take the SIM out, it always asks the pin from my SIM card after the starting process.

Thank you very much for your reply. There is no SIM inside when you are starting the iPhone. Is this then normal that the device is asking for the PIN without a SIM?
