I replaced the battery in my iPhone 4s (also unplugged the antenna when I did this), after replacing and reconnecting I plugged it back into iTunes and updated to 6.0.1 (At which point it said there are Carrier Update Settings for my iPhone, I clicked OK) and now I have lost reception completely and just says "No Service" in the top left corner.. My wifi works fine, Bluetooth works fine, everything seems to be OK besides my network reception. I have checked everything... took the phone apart again and checked the antenna connection, battery connection, checked the ground clip for the back panel, everything I had touched when replacing the battery. I also noticed that when I try a "field test" ( Dial *3001#12345#* ) it proceeds to the Field Test Mode at which point it just sits there with "Connecting..." in the bottom left corner and it WILL NOT connect no matter how long I let it sit there and do it's thing. I tried it with my old Iphone 4 and it gives me a readout even without a sim card.. I tried the 4S without a sim card and it still does the same thing, "Connecting...". I have since tried going to "Reset Network Settings" and even going as far as completely re-installing 6.0.1 in DFU mode several times, both without any success. Even tried with 3G On/Off, and turned Carrier Selection to Manual, no dice..

P.S. - I have also checked the "Blue Inductor Coil" and it appears to be fine as well. And I know the SIM is OK because I tried it in two different iPhones and it worked.

Any help would be appreciated... I'm going to order a new Dock Connector/Loudspeaker/Antenna cable and try it in the meantime..
