iPad still pending FCC approval, not a problem
Did Apple just announce a "magical and revolutionary product" that they can't yet sell? Yes and no. Yes, given that the 3G iPads will connect to the cell phone network, the FCC will have to approve them. But will that be a problem? Probably not. As our own Mike Rose would say, Apple prefers to announce their products themselves, and they'd rather not have them leaked by a government filing (since any applications filed with the FCC would find their way out to, well, this very Unofficial Apple Weblog).This device has not yet been authorized as required by the rules of the Federal Communications Commission. This device is not, and may not be, offered for sale or lease, or sold or leased, until authorization is obtained.
So it's no surprise Apple has waited until after their announcement to secure FCC approval, and it's very likely that they'll get that approval long before the 90 days until the 3G iPad's release are up. That notice on the page is a formality, and even if the FCC has an issue with the iPad, Apple has plenty of time to fix it.
