added the cellular ip for ios

[ArshanKhanifar]

So I basically modified the method such that it will now return the cellular ip address, if the phone is not connected to wifi.

output: connected via wifi : x.x.x.x
output: connected via cell : x.x.x.x

This only works for ios.

Please let me know if it has any problems.

Is it possible to pass the interface back to the calling function? Therefore the app calling can decide how to use the IP (if it doesn't want to handle cell IP's, for example). Something like:

networkinterface.getIPAddress(function (ip,conn) { alert("connected via " + conn + ": " + ip); });

I don't have the time right now to spend on fixing this but it would be greatly appreciated improvement. I also would like to get this working for other platforms as well.

Thank you!
