Apple rolled out the settings screen and info on activating, adding, etc. to the 3G iPad service through AT&T. Any speculation as to whether this can be done on the fly through the 3G service or if it will require a WiFi link to activate? What would be great is that even if the 3G service is not in effect, if you could connect to AT&T via 3G to activate it rather than having to have a WiFi signal to sign up or reactivate. Isn't that the point. If you need a month of service, you should have to plan ahead or have be able to activate it on the fly. This would make the 3G a much bigger selling point. Otherwise I'm probably not interested.
