Why? How about to make money! Plus, T-Mobile includes a headset with every phone.

The real question ought to be why do people, before the product even hits store shelves,
do their level best to rip the thing apart?

2nd such rumor....one from each side of the Atlantic. There has to be some smoke to this one.

GSM can utilize CDMA technology for transmissions. Don't confuse JS-008 and CDMA. Its not as tricky a proposition as one would think.

T-Mobile for the consumer side, Sprint/Nextel for the business side. GSM for voice, JS-008 for data. Hmm.

The Sprint-Nextel merger difficulties have had far more to do with corporate culture & product management issues than technological issues.

Its not like 85% of households have dumped their home phones in favor of cell phones. Actually, its about 15%. The average home phone user isn't an ubergeek who gets on a techno message board. The cost of the setup is less than half per month what a traditional VoIP is, and the customer already would be getting a T-Mobile bill. This program has a chance to be an attractive add on.
