iPhone 4 3G 'no service' 'searching...' And 'SOS only'
I have replaced many parts of my iPhone 4 and have had many problems after replacing certain parts. The problem i have now is with 3G and sending and recieving calls and texts. I have looked online and have been told to check if the little antenna right next to where the battery joins is connected properly and it is. I am thinking it is a motherboard issue but I am stuck as to what to do now.
