Not sure what you are describing. Is your SIM Card installed in the SIM Tray in the iPhone? If not, install SIM Card into SIM Tray.

I had the EXACT same thing and I have appeared to fix it thanks to Amand99:
1) Make Sure you are running latest Itunes.
2) Plug usb cord into computer with itunes on. DO NOT PLUG INTO PHONE.
3) Do a hard shut down of your phone, where you hold the home and lock button and don't let go until the phone completely dies.
4) Hold down home button for three seconds. DO NOT LET GO. While continuing to hold, plug chord into phone, connecting it to computer. DO NOT LET GO. Hold for an additional five seconds.
5) A window should appear in itunes saying that a phone is connected which needs a system restore.
6) Itunes should allow you to restore and update.
7) Now this was key for me because this might have been my mistake which originally caused this issue. After the restore, Itunes shows the iPhone grey with a spinning wheel (like bofore). I looked at the iPhone and it looked like it wanted me to go through the setup options. DON'T TOUCH THE PHONE. Be Patient, iTunes will eventually recognize the phone and finally ask if you want to restore it. Choose "restore from backup", and let iTunes do it's stuff.
My iPhone is back, Baby! <phew>
