Loss of signal, but WiFi works
Hi, I have an iphone 4 with ios 7.0.2... My problem is that the phone while it is running normally, suddenly loses signal, and stays on "Searching...". The curious thing is that the WiFi still works perfectly, so I think it isn't a hardware problem of the antenna, which I also already tried to clean up... I also tried a full reset with the DFU mode, but nothing... What can I try? Thanks to all!
Es esta una buena pregunta?
