    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
