Mike, re HDR and GSM--I remembered it wrong, but not completely. Here's the link, describing an Irwin jacobs presentation on where they are going, to CDG (a link to his presentation is provided):

Message 13900488

and the relevant part of the roadmap:

d)1X MC & 1X MX w/HDR support the "GSM MAP NETWORK". I take this to mean that IX MC is designed to support an overlay of MC CDMA over GSM. QCOM's future DS-CDMA chips will do the same.

Support of GSM vs. the GSM map network are different things, of course. Still, my point is that QCOM is facing the "threat" as a GSM threat, not a TDMA threat. They are designing products to allow the next generation to be installed in GSM territory.

Re TDMA's compatibility with GSM--That's my understanding, too. Yes, they are a "hop. skip and jump" from one another. They do require separate R&D and product development efforts. A product built just for GSM won't work on ATT's network. I don't know how complicated it is to make a dual-mode GSM/TDMA phone, or a GSM/CDMA phone (actually, they'd be tri-mode, assuming you include analog).

And, I should have said, "SBC and new-ATT/former-Verizon conversions." As you concluded.
