Which network will Apple's tablet flood?

For a device that hasn't even been confirmed by its maker, Apple's enigmatic tablet has attracted much speculation about its potentially game-changing features. The tablet is still just the subject of rumor, but industry analysts, tech pundits and Apple fanboys alike are placing a lot of stock in it, hyping it as the first versatile device to fit perfectly in the middle ground between cell phone and PC. It could be a computing device, e-reader, gaming console, music player and access to Apple's vast ecosystem of third-party applications. And presumably it will have some kind of 3G connection. For the wireless operators, landing such a potentially powerful device would be a coup for their mobile data businesses, but it could also wreck their wireless data networks.
