I just wish someone would release a phone that allows two NAMS to be active
at once. I hate having to carry around two phones (one for work, one
personal).

Nigel, are you enjoying high-speed connectivity without paying for a
separate data service?

I'm not sure about that. I think the ESN's are on the SIM. The Siemens
phone offered by ATT which did both GSM and TDMA did not utilize the GAIT
standard to do it. Cingular has specific SIMs for GAIT phones. CDMA phones
in China utilize a SIM so the standard is in place for a CDMA SIM. Nextel
has also implemented the SIM for iDEN.

While I agree that the problem of double use of the SIM in Europe and in the
US simultaneously would be minimal, remember that they will probably want to
rent these phones to persons coming to the US. I suspect that this phone
will be going on sale in Korea as well for obvious reasons.

I would be willing to bet it works like a GAIT phone does. GAIT phones

Actually, the Cingular GAIT sims work differently. I have two GAIT
phones - T62u, and 6340i. I can put the SIM in the 6340i, and it works
with GSM systems, but not TDMA or AMPS. I can also put the SIM in a GSM
only phone, and it works just fine. A GSM SIM from a GSM nation plan
also works in the GAIT phone with no problems. My SIM was activate
while I was roaming in a TDMA only area, but I don't think that should
make a difference.

GPRS isn't really high speed, about 50-60Kbps generally.

The price is right, $20/month unlimited access. Far cheaper than Verizon's
Express Network at $80/month
