It doesn't matter what it means really. As long as it does what they need it to do. 3G allows me to stream music from Google Play and watch YouTube videos. I hot-spot my MBP to it all the time. 4G is faster but not noticeable unless the stream stalls. The most frustrating thing is if there is no data connection at all to speak of.
