I just realized today that my Sprint iPhone 4S allows me to talk and surf (and do other stuff) at the same time. Supposedly, you couldn't do that with Verizon iPhones. Is that still true? Did something change in iOS 5 or with the iPhone 4S to allow simultaneous talking and surfing at the same time?
BTW, I was at home, so maybe I could surf on wi-fi while talking on the cellular network?
Just curious ...
