keynote is still ongoing, but one tidbit that we have to bring you immediately: we have a launch date for the iPhone 2.0 firmware and the iTunes App Store, "early July." iPhone users get the upgrade free of charge, and iPod touch users can download it for a $9.95 charge. Applications under 10 MB can be downloaded over the cellular network, and larger apps can be delivered over WiFi or via an iTunes sync.
Enterprise users can deliver apps directly to their users, and there's also an 'ad-hoc' delivery method for up to 100 iPhones.
