iphone 4 losing 3G signal
Lately my iphone 4 has been losing 3G signal and in its place is a little circle. It is also running very hot? Any answers are appreciated!
iPhone 4, iOS 6.1.3
The circle is the GPRS or 1xRTT connection. It means your phone is still connected to your cellular provider's network, but at a very low connection. This is a cellular carrier issue. Contact your wireless provider.
