My iPhone 4s doesn't detect any wifi
First please forget my English, I'm French. My problem is that my iPhone 4s doesn't find any wifi. I've tried to reset the network and wifi. I opened it and saw if the antenna was connected (it was). I bought a new wifi and Bluetooth antenna and changed the old one, but it still doesn't work. I've no more idea. Please, it would be kind if someone could tell me what can I do to fix my problem. I've never taken my iPhone in for repairs nor have I opened it before my actual wifi failure. Thanks
