Not really, tha name has just been announced and I assume this is meant to be used in a radically different way than the previous ones. Note that it's called "iPhone 4S".
Then again, some people might have been using it that way already.

Check out the beginning of the "Technical Description" section:

AFAIK, the temporary storage server is on the carrier's premises and contain the images / media / whatever that the MMS carries. The data connection you do need to retrieve those attachments is therefore limited in scope and the carrier can safely establish a policy of not billing the recipient for accessing this temporary storage server. He has already charged the originated party (or the interconnect carrier) for delivering the message + attachments to the recipient.

Of course, this is entirely open for whatever policy the carrier chooses to apply; there are countries where you even pay a fee to receive calls on your mobile phone, and smaller fees are charged to whoever is originating the calls - since it's the recipient's choice to carry a mobile terminal instead of having a fixed landline, he's the one paying for that traffic.
That's not the most generalized behavior though; usually mobile subscribers do not pay for received calls, SMS or MMS (including attachments), except perhaps when roaming abroad - and even then, usually received SMS (and only those) are not charged at all.

I agree, you should have posted on Digg instead.

Bonus points will be awarded for submissions somewhat related to this usage scenario.

Also mod parent up, nice pun.

Another aspect claimed by the article is that even with Hibernate there is still some power drain, altough below 1W.
I do know that my laptop had Wake-on-LAN turned on in the BIOS. After disabling it, I stopped noticing 1% or 2% missing charge after being hibernated for a couple of days without being plugged in.
