I replaced mt screen and when I put my iPhone 4 back together and turn it on it wont read my sim or any other sim. T he WiFi and everything else works except for the sim. I checked everything and made sure everything was in the right place. Any help, what can I do?

You don't have the antenna cable in all the way. It's the little black cable that comes from the dock module.

Is it that little small black wire running next to the battery and on top of the speakers?

Yesterday you said something about SIM tray screws and you thought you had them wrong. That's worth a revisit I think.

I made sure everything was in place by looking on another iPhone 4. I feel so bad, did I just break my phone :(

Can you try to put back your old screen and check if it is working, we had one case here that could not get the signal with a new screen, not sure whats wrong with these screens!

I also did that today I placed all the original pats back. Everything works except the phone finding my sim. I also just restored it and nothing.

Check the pins on the sim card slot, are they all there or any of them broken? Also check your SIM card on another working phone.

All pins are there and the sim works on my newer iPhone 4. I also tried my my wife's iPhone sim and nothing. I really appreciate the help. I will take pictures today and post them up see if you can spot anything.
