Before I get tons of questions, no it is unfortunately not a real iPhone 4G. There's no new iPhone, and it's not the 4th generation. This is Sprint saying "Oh hey AT&T, we can make the iPhone ten times faster. So yeah, might want to think about that."

In the commercial below, Sprint is offering up their wireless 4G network to be used as a WiFi network on the iPhone. That will supposedly make the phone run up to 10 times faster just by connecting to the WiFi. It's available in a personal wireless router, often called a MiFi. They also take the time out to mock AT&T's 3G speeds. Looks like AT&T now has two enemies to fight.
