You have damaged your iPhone or your SIM card.
If you have another phone, you could test your SIM card by putting it into it. If it works, then it's likely an issue with your iPhone. If you can borrow a friend's SIM card, you can try putting that in your iPhone. If it works then you know you have a problem with your SIM card.
In either case, you should talk to your service provider to see if they can repair it for you.

Please wipe the SIM slot clean... As well as the SIM.. This might sound odd, you may also try charging the phone for a while.. It works on me anyway

Calm down. Could be a number of things causing lost service. Restart the PC with iphone disconnected. Bring up itunes, plug in iphone and let the activation sit for a couple of minutes. If status does not change about sim card, eject the sim card using a paper clip, insert that paper clip into the tiny hole on the top of the phone. disconnect the phone, insert the card again, and reconnect. Let me know if this helps.
