What Exactly Is ‘4G’?
First and foremost, there is no "iPhone 4G." This is a misnomer created by people who don’t know what’s what. Whatever Apple decides to call the next version of the iPhone, it most likely won’t be the 4G — for several reasons. The iPhone 3G was called the 3G because it added 3G to what was previously a 2.5G device. T he likelihood of Apple adding a 4G radio to support 4G networks that aren’t even available yet is slim to none. And while the 2010 iPhone will be the fourth version of the iPhone, I believe Apple is smart enough to avoid the 4G label. So what, then, is 4G?
