3G is too slow. I know that from personal experience--but if someone did make a 4G card and it worked with every device from laptops to the 3DS (sorry PSV--you decided to use your own bullshit format.....), I could see more people giving it a shot. Not me, unless it was able to be added to my current cell phone plan for free.....or for ten dollar more, max.
Anyway, it's a great idea, Galaki. Wouldn't be surprised if somebody actually does it some day.
Also, let me point out that I've never used a 4G device. It may very well be just as bad for gaming as my current 3G device.
