About to buy an iPhone 3GS. We live in a valley with poor signal strength. Need an app that provides WiFi calling. Would like to be able to set the phone so it will make use of the strongest signal, either cell phone tower of WiFi, for both making and receiving calls.
I realize the phone needs enough of a signal to register an incoming call. We have that but the signal is often low enough that the call is often lost. Would like an app to switch over to a good WiFi connection if the tower signal is too low.
Had another phone once that made WiFi calls but only if you set it before a call was made and only for that call. Did not work for receiving calls.
Anyone know of a good app that will work this way?
