I did the usual stuff, reboot, reset sim, battery, charge, etc. No dice.
I took out my SIM and put it in my wifes phone. No signal. I put my wifes SIM in my phone, full signal.
Looks like the phones modem is fubared. I rooted my phone and install SHOstock3 v4.0. If I do the same to my wifes phone, do you think that will alleviate the problem (not recognizing the SIM)?
