Basically MMS = SMS + Attachment. Everyone should at least read the Wiki on MMS.Ok. I'm talking about VOICE and EDGE "data" usage simultaneously. I'm not saying anything about MMS and EDGE data usage simultaneously... as far as I'm concerned, they're Apples and Apples.
So, to recap, I was expecting a statement more like this: "Indeed, it is physically possible for some phones connected to EDGE networks to send/receive MMS data transfers while conducting normal cellular voice operations."
To illustrate, THIS is the disagreement we SHOULD be having (if we disagree at all). This is a conversation copied from the Howard Forum website in June of 2006:
So, in our case... I'm agreeing with baaadandy's comments, and perhaps erroneously (maybe someone can enlighten me) adding that MMS is NOT the same as SMS and travels a similar route as other data transmissions (thus preventing simultaneous voice usage on an EDGE network).
--This, in turn, would mean that usage of MMS is much more problematic for these phones, than phones with more modern 3G radios. In this day and age, you might even say that its so "lame", that, even if you could get it working consistently the way one would expect... it would spur a plethora of phone calls from EDGE users, wondering why they encounter certain unintuitive technical issues that 3G users do not.
Jut look at Swirly MMS technical complaints on both T-Mobile and ATT&T. Some of it sounds like carrier issues, others sound like technical glitches related to how reliably the technology works on EDGE.
Indeed it does, droobie.

WAP (traditionally) is used to retrieve the attachment. In this case the WAP may be pointing to a http server of some sort.
