Just Asking

I recall that the initial iPhone announcement was driven, in part, because FCC rules required advance disclosure of handset details as part of the approval process. Would the 3G iPhone be subject to similar rules? Will any official statement merely be timed to match FCC issuance of details? Or have the details already been made public (I'm pretty sure not as 3G is still a "rumor"). Or is 3G similar enough to 2.5G that no new filings will be necessary?
