In my application I need to check network type GSM or CDMA (for Verizon). I found CTCarrier class which contains property mobileNetworkCode, but I don't wanna hardcode value for each providers. Are there other ways to check it?
Please help.

回答1:
You could get that through the Model#, but then again, you have to hardcode a list of Model# and compare them.

Maybe you could do that by checking the IP Address of the iPhone if it is wireless connected. If once detected it would´t change unless you change the SIM ;-)
At http://www.tcpiputils.com/browse/ip-address/192.76.85.245 you get information on verizon IP space
