Yeah, most people won't be able to tell the difference between 3G and 4G in real world use. But it will matter in marketing (just like in megapixels in cameras). People think that higher numbers = better. So they'll see 3G in some phones and 4G on others and assume 4G must be better.
So I hope the next iPhone has 4G even if few people can make use of it.
