Re: Well... it's dated info...

AT&T's legacy network is actually more correctly described as IS-136. Both IS-136 and GSM are TDMA technologies; calling one or the other TDMA isn't technically correct (and AT&T's way of doing that really annoys those of us who know the truth :)). AT&T is actually deploying/deployed a GSM network, now - I think New England is covered under it. A friend of mine on their old IS-136 network hated it and got rid of it as soon as he could.

For a pretty detailed description of CDMA vs. TDMA, if you care, check out this site - it goes into a decent amount of detail about all of the differences between the various transmission methods, protocols, and codecs, including the capacity handling differences that you mentioned.
