For all you guys saying AT&T or Verizon's networks are years away from 4G, America isn't the only country in the world you know. 🙄
A few Asian countries, and many European have already begun rolling out real, 100Mbps, 4G networks. Yes, cities in the UK and Sweden can access 4G networks right now.
What? Apple's an American company and will support only what America needs? Not in my experience, really. I've been using the bluetooth in my PowerBook to connect to my cellphone since 2003, when most American Mac-owners were calling it a useless feature because US carriers blocked bluetooth support on phones but Apple still supported it for the lucky people in the rest of the world. There's also MMS in the iPhone -do American iPhones support MMS now, by the way? Tethering? Emoji?
Apple do support features for other countries, even if it doesn't work in America.
So I don't think it's such a stupid question to ask if Apple will release a 4G iPad soon. They're also always the first company to support the latest WiFi standards, so I don't think it's too outlandish to suggest they might have a 4G enabled iPad within 2 revisions of the device - possibly even by the next generation of the iPad if Apple has access to a dual 3G/4G chipset.
